1. Apparently I am suddenly interested in lots of different sports. I vaguely remember watching bits of the last Olympics, just because it was on, and I was bored, and I liked TV. This year, I actually seem to care how well we do. This is a weird development for someone who hates sport, and I don’t like it.
2. The BBC page is brilliant, of course, with live video and an automatically updating commentary. However, the medals table doesn’t automatically update. This is an oversight, I think, but then again, it’s not like we win enough medals to make it worth the coding time.
3. Apparently there is a maximum size on the women’s volleyball outfits. And there’s me thinking volleyball was just about pretty ladies running around in next to nothing on a beach.
4. Interesting that we were all blown away by the opening ceremony, and panicking that we would never be able to match it in 2012 (we won’t), but it was all fake. The footage of fireworks was shot on a previous night, and the iconic cute little girl singing was actually voiced by another girl behind the scenes.
5. The best bit of action I’ve seen so far, as described by the BBC Live commentary team:

1537: One of those things on TV that you shouldn’t laugh at but can’t help yourself, a Russian weightlifter failing to make a lift and staggering off the stage with her head in her hands before walking into a wall. As Mel Brooks once said: “Tragedy is when I cut my finger. Comedy is when you walk into an open sewer and die.”
