I believe that everyone should be using Firefox as their browser, but if you're a blogger and need another reason to make the switch, here's one. Performancing is a Firefox extension that allows quick, full capacity blog posting from anywhere you may roam on the net. Once installed, you fill in all our blogging information (what service you use, username,etc) then it just sits as a little icon in the lower right corner of the browser. Click on it anytime and a pane pops up that lets you fully compose and post to your blog.
