Actually, a lot higher than that actually.
“In probability theory, the birthday paradox states that in a group of 23 (or more) randomly chosen people, there is more than 50% probability that some pair of them will have the same birthday. For 57 or more people, the probability is more than 99%…”
Drop one of the ‘actually’s.
Beware the biased sample of respondents!
Someone whose birthday is the same as yours would have been more likely to notice your daily blogg about a birthday and more likely to leave a comment there since they had something special to add.
Will’s comment above is correct, but only for a random sample.
Hope this makes sense and I’m not being a kill-joy!
Well, I found Daniel’s blog from ToxicCustard, when that used to get published on Usenet. Actually, I say “used to” – I haven’t been on Usenet in 2 years, so I have no idea whether it’s still there.
I noticed we share a birthday last year too, and posted to say so. So I’m not one of the “ooh this guy’s got my birthday also lets stalk him on his blog” crowd :)

It’s rather interesting.
