an experiment:

http://snipurl.com/bf5h

http://tinyurl.com/6rm7x

edit: I used a known long url that I had sent someone, generated via snip (I guess they save these in a data base for a while as I was informed "We have snipped this URL before") and ran the same address through tiny.

there seems to be one tiny advantage to using snip; it automagically pastes your paste buffer into the text box, thereby saving you one tiny step.

ASp, notice that I didn't claim an advantage for snip based on length, as it was only one try.
