Twitter is a lot of things to a lot of people, but "pretty" isn't really the first one that comes to mind. It doesn't have to be that way, though, because you can give Twitter a clean, minimal new look with Helvetwitter. It's a script that lets you view the Twitter website in black and red, with all the type in Helvetica, and plenty of white space for all the words to breathe. This may sound somewhat familiar, because it's inspired by the' Helvetireader script for Google Reader, which made my list of the 10 best Greasemonkey scripts.

Helvetwitter isn't perfect for everyone. One if its big pluses is that it doesn't use the entire area of your browser window, so you can shrink Twitter down and drag it off to the side of your screen. On the other hand, the lack of icons can make it harder to pick out whose tweets you're reading at a glance. The lack of sidebar is both a plus and a minus: I personally don't miss it, but you might if you actually care about trending topics. You can install Helvetwitter in Greasemonkey if you use Firefox, and the site offers instructions on how to set it up on other browsers.
