A couple of plug ins to rule them all.

First thing that gets installed on new browsers (Firefox, Chrome) lately is Shareaholic. It allows me to clip items to Evernote and quickly share links and notes through Twitter and Facebook. It links to plenty of other services but, oddly, not Movable Type blogs. So, second thing that gets installed is Scribefire. Two extensions and I'm ready to go! Oh, and Xmarks. Ok, that's it.
