Fixing Facebook
So Facebook is having a bad-hair day. However, with a little custom CSS, some aspects of the site can be restored to how they were previously. Most web browsers allow the user to over-ride parts of a site’s style-sheet with those from a user-supplied style-sheet. For instructions on how to set the user style-sheet for your browser, see User Stylesheets.
Among the changes that are most irksome aesthetically are the rounded corners on thumbnails and the now overly large wall font. These changes can be negated with the following CSS over-rides:
.UIRoundedImage_Corners{display:none !important;}
.UIIntentionalStory_Message{font-size: 11px !important;}
There are a lot of other changes to Facebook that I find annoying, and when I find the spare-time, I’ll probably find ways to overcome these. In the mean-time, check-out userstyles.org for more comprehensive user style-sheets.

How can you not like the rounded edges!? They’re so Web 2.0-ey
Rounded edges work when they’re done properly and not along side a lot of sharp, straight edges. I really do think Facebook brought out the fug with its latest update. Having said that, yes, they are tres web 2.0.
They’re like for kids who can’t handle sharp things yet!
