What is this you ask? a) it is a strangely addictive game b) it is an experiment for a blog post I'll be writing on user experience design -- particularly around offline IA. Some more info here: joshrweinstein.com
I still prefer the abstractness of <a href="http://www.clickyourlifeaway.com" rel="nofollow">http://www.clickyourlifeaway.com</a><p>-edit - but I like the submission by the OP too, I can see it becoming a meme XD
So I'm guessing the experiment is either A/B testing of layouts of number pads, or it's testing to see if people can cheat the leaderboard.<p>Also, it must be a slow news day for this to get to front page.
yeah I have no clue what it is... and I even read the blog. Pretty sure it does not count as a game or an experiment with so little explanation... who knows?
