Interesting and fun.

You get to see the words before you enter the URL, which gives you some choice in matching up words to URLs. I also noticed that it lets you add the same URL twice:

http://s.mashd.cc/nonsubstantiality

http://s.mashd.cc/mispage

Yes, it lets you use the same URL twice - bit.ly does the same. Potentially different people want to share the same link and see their own stats:

http://s.mashd.cc/stats/nonsubstantiality http://s.mashd.cc/stats/mispage

...although I see I have a but with the impact calculation :)
