Good post to have stuck at the top :)

Just a heads up for those people like me who hate being rick rolled by masked URL's.
"Bit.ly preview" is a plugin for FireFox (https://addons.mozilla.org/en-US/firefox/addon/10297)
When you hover over a shortened link, the real link is displayed. Works on bit.ly, tinyurl, and I just tried a cli.gs link and it works. (probably works on others as well)

Anyway, just thought I would let you know.

Cheers
James
