I dunno if it’s hard or not (not a programmer), but maybe you’d want to have Newsblur added to the browser extension AddThis? It’d be nice to just right-click anywhere on the web to share something on Newsblur.
This page seems to tell you how to do it:

No worries if not, hehe.
Edit: You know, now that I’ve messed around with Newsblur’s social stuff a bit I guess I’m also asking a larger question: how about the ability to share stuff from sites whose feeds we do not subscribe to in Newsblur?
Like, I just ran into a cool Youtube video and my first thought was to put it on my blurblog. Is that outside the scope of the site?
