I'm using LodgeIt( http://paste.pocoo.org ) for my paste site of choice. When I was using vim, I was copying the text and pasting it to LodgeIt manually but since I have a opportunity to write plugins in a language I have experience with, I thought it's a great way to automatize one of my routines.
I'm using this mostly when I'm in a need of pasting some code to an IRC channel or some other IM environment.

Any comments/criticism/feature requests will be appreciated.
