In the Olympic Games there's a temptation to measure greatness by the number of medals won. This carries a bias towards those who enter many events and do well in most or all of them. On the other hand, there are those who enter only one event because that's what they specialise in, or that's all that's available. And among those athletes, those who came back Olympiad after Olympiad and keep on winning their one gold. Think Steve Redgrave or Al Oerter.

23:54 Is it true that Clive Palmer is bidding for Titanic class to be added to the sailing program for Rio 2016? #
23:43 That sound you hear is of all the Government funding shifting from swimming to sailing. #london2012 #
23:40 Congratulations, also, to Pavlos Kontides: second in the Men's Laser, and the first Cypriot Olympic medallist ever. #london2012 #sailing #
23:36 All right Australia! #london2012 #sailing #
23:28 I'm enjoying this coverage of the #sailing. Why haven't we seen far far more? #ch9 #london2012 #
23:12 The complete series of The Guardian's #London2012 Lego reconstructions. I can't wait for the greco-roman wrestling http://t.co/m0b3rf5g #
23:10 The Guardian's sublime Lego recreation of the #mens100m final. And I still feel Asafa Powell's pain. #london2012 http://t.co/xVKJ05Kq #
23:00 Go Australia! Go Cyprus! Go both! #london2012 #sailing #
22:59 My latest #London2012 blog post, on sponsorship, #Rule40, ambush marketing and bottle-throwing - http://t.co/gVJf2qQU #
21:36 Dear #qanda, what is the best method to microwave meat pies without making them soggy. Thanks. #auspol #sideshow #
21:29 Shar-kies! Shar-kies! Shar-kies! #london2012 #waterpolo #
20:34 So the only person standing in the way of Cyprus' first ever gold medal is an Australian :/ #london2012 #sailing #
20:21 though a post-Games performance review should be de rigeur anyhow. #london2012 #swimming #
20:18 The Olympics aren't finished and the swimmers aren't home so why is Swimming Australia issuing statements like this - http://t.co/cg6uecYh #
20:11 Umm, why the smiley? RT @rhinorevolution: Poacher Dies in Shoot-out....:) http://t.co/fwRkQyqi #
19:57 So how does a Twitter account pretending to be a Martian space probe get a "verified" tick? @MarsCuriosity #
18:24 @Bill2063 eliminated in a fair selection process. I have no inside knowledge on how NASA recruits its staff #
16:30 And in other news, some members of the South Sydney Rabbitohs are not called Burgess. #nrl #
16:22 another video rental store bites the dust. Just Movies at Stanmore has closed its doors #
16:02 and yes, I witnessed both those events on live TV :p #
15:58 1969: "Tranquility Base here, the Eagle has landed." 2012: "We've got thumbnails!" #
15:39 I'm still looking for the African-Americans in the room. #curiosity #diversity #
15:37 We've got thumbnails. #msl #thumbnails #
15:33 I think they did it. #msl #
15:32 Come on we need some more "whoop whoop whoop yee ha!" #msl #

It's like the good old days of Moscow, Los Angeles and Seoul again, when Australian gold medals were rare events to be savoured, not the passe quota-fillers of Athens and Beijing. On the tenth official day of competition, Tom Slingsby has taken out the men's laser event in the sailing competition to deliver Australia's second gold medal of the London Olympic Games, nine days after winning its first.

Just behind the starting blocks, just before the start of The Great Race - won by Usain Bolt - a bottle was thrown on the tracks. There was no harm, no disruption, but a serious breach of security.

In the end, the result was beyond doubt. One of the greatest 100 metres fields of all time, but Usain Bolt still blitzed them.

23:35 Gonzalez Sepulveda should have won a gold medal for that moustache alone. #london2012 #gymnastics #chile #
23:29 another #london2012 blog post from me http://t.co/8igTQZpM #
23:24 So close. Malaysia still waiting for its first ever gold medal. All their medals have been in #badminton. #london2012 #
23:17 come on Malaysia! #london2012 #badminton #
22:56 @Bill2063 yes, and this time, they've hidden Eddie commentating on a 2.5-hour marathon #
22:50 Williams and Williams have won #tennis gold for the USA http://t.co/5eU6h5Ur #london2012 #
22:46 who needs Foxtel when I have squillions of tabs open to the http://t.co/cw2vmRBx website? #london2012 #
22:45 Frederik Loof has just won a gold medal for Sweden. No relation, I trust, to Loof Lirpa. #london2012 #sailing #
22:35 and we cut away after the first round of an historic fight to replay an interview that we screened earlier. #ch9 #london2012 #
22:30 Much as I believe #boxing shouldn't be in the Olympics, the start of the first women's competition is a historic milestone. #london2012 #
22:15 Cyprus will win its first ever Olympic medal on Monday. http://t.co/OozaTNhg #london2012 #sailing #
21:32 sports betting ads I'd like to see: that dude taps on the airplane window and Tom Waterhouse gets sucked out #
21:30 So does the Australian swimming team observe Mad Monday tomorrow? #london2012 #
20:03 @Jono he was starting the marathon "within sight of Westminster, er, Buckingham Palace" #
19:56 Eddie stuffs up London geography in the opening sentence of his ch9 commentary today. This'll be good. #
19:08 You can tell there's no women's #beachvolleyball on at the moment. #ch9 #london2012 #
18:52 A rare highlight from ch9: the studio panel of Daley Thompson, Michael Johnson, Linford Christie previewing the #mens100m. #london2012 #
08:42 In a busy #london2012 Saturday, Damien Hooper's elimination in the boxing risks being overlooked - http://t.co/Sf6VKM9G #
07:48 Never mind the traditional Anglo-Aussie sledging. I am so happy for Great Britain. Congratulations, what a day :) #london2012 #
07:41 Just watching the mens 10k on delay. Mo Farah. Wow. #london2012 #
07:36 But it looks like the #WIvNZ Test at Sabina Park, Kingston will be all over before Bolt/Blake/Powell's final tomorrow. #london2012 #cricket #
07:34 Play was interrupted in the #WIvNZ Test #cricket in Kingston for the running of the #womens100m final. #
07:28 One of those mornings where I slept in an hour longer than planned and have been playing catchup with Olympic news ever since. #london2012 #
06:58 Fraser-Pryce wins again! #london2012 #womens100m #

Was Saturday Great Britain's finest-ever day of sport? I'll leave that to the historians.

23:41 My mid-Saturday #london2012 blog post with bonus Dong Dong - http://t.co/iyJqtbgx #
23:17 Warning warning: MENS #Beachvolleyball on ch9 following the break!! #london2012 #nedvsui #
22:31 Wow. RT @London2012: Pic: For anyone who blinked, here is the photo finish from the women’s #Triathlon earlier today http://t.co/fAxj34Dl #
22:30 Just visited a website offering "world class translation and interpreting services". Quotes Nelson Mandela but spells his name wrong. #
22:19 Dwain Chambers 10.02. #london2012 #mens100m #
21:55 10.08. Cruisin. #london2012 #mens100m #bolt #
21:52 Bailey 9.88. Now it's Bolt time. #london2012 #mens100m #
21:49 Massive win by Knapkova. Kim Crow 3rd. #london2012 #rowing #
21:43 I think we can give this gold medal to the Czech Republic now. #london2012 #rowing #
21:38 How the 2004 Olympics Triggered Greece's Decline http://t.co/z6c6cb4U via @BW #
21:08 All rise as Neil Young sings the National Anthem of Great Britain: http://t.co/9f1Rldoq #
21:03 there are times when it's too soon to do post-race interviews. I'm watching one of them. #london2012 #rowing #
20:58 And that should put GB ahead of South Korea on the gold medal count with 10. #london2012 #rowing #
20:43 Looks like the second week of Big Brother promos are going to be even more obnoxious than the first. #
20:38 that puts Australia's silver count into double figures, yes? #london2012 #
20:37 @melburnian the Paralympics will be on the ABC #
20:36 Team GB again! #london2012 #rowing #
20:00 Wow. what a close finish! #london2012 #triathlon #
19:52 All right. This looks good. #london2012 #triathlon #
19:37 Pistorius will qualify for the next round. He made it look effortless. #london2012 #mens400m #
19:33 Oscar Pistorius is on the track! #london2012 #
19:09 Looks like I'm switching ch9 off forever once the Olympics are over. #bigbrother #farmerwantsawife #howzat #
19:02 Australia 1 South Africa 0. They'll probably need for and against to qualify. Are they doing enough? #london2012 #hockey #
18:26 haha. ch9 going out of their way to show both NZ and Australia on the medals tally. #london2012 #
18:21 my latest #london2012 blog with random stuff I haven't mentioned before http://t.co/Usheojta #
18:10 I'm sorry but the Wales brothers giving a TV interview is not, in itself, news. #9newsat6 #
18:01 "A channel 9 exclusive: How much you're paying for asylum seekers." Can I be bothered hanging around for this? #9newsat6 #
16:46 GWS Giants second win. Can the Australian Olympic team match them? #london2012 #aflgiantspower #

Big busy Saturday morning and afternoon at the Triple-X Olympiad. Some highlights:

It's one whole week since the opening of the Games of the Triple-x Olympiad. As that traditional Australian saying goes: There are no winners and losers, just silver medallists. Here are a few random items from the first seven days that I haven't previously mentioned:
