This is the latest site to be launched by leadingmedia and what tweetfacts does is finds all the tweets that have the phrase "did you know", which obviously implies that a fact is to follow.
The site can actually be used as a tool for research, as I have discovered new things today, for example "Did you know: A new idea lasts only about 40 sec in the short-term memory! Make sure your write these down before they are gone forever!" and " Did you know that isset($str{5}) is 176% faster than strlen($str) > 5?"
The site is pretty cool to just browse around and find out some pretty interesting facts that you most likely did not know, and the beauty is that when you're done reading you can just refresh, and knowing the active twitter community, you can read a whole new set of facts!
Thanks,
Richard
