I wrote this Simple Curiosity post on 'Why Time Slows Down When Approaching the Speed of Light' a while ago. In fact it wa on the Simple Curiosity blog that I've closed and now host on this site.
Someone found that post and Stumbled it, leading to an extra 20,000 page views in the last 48 hours and the addition of 700 RSS readers. Shazam!
Of course, now I'll have to start writing Simple Curiosity? again to keep those RSS readers happy.
