TwitSnip is a simple bookmarklet tool for easily posting to Twitter. It lets you “quote” text on any web page. It does nifty things like looking up the @user for the website and linking back to the source. It shortens the URL too. It even tries to shorten the length of the tweet (when needed) using a twitabulary of short words. TwitSnip works in Firefox, Safari, Chrome, and Internet Explorer.
