My wife and I maintain a silly blog of little importance (currently MT, hope to move to WP). We're upping the post frequency, and realized all our posts visually blend together. What I'd like is a means to style our posts differently based on the user and category. Something simple like changing the background color of the block. My posts might be light gray, hers light blue, that sort of thing. We don't actually use categories yet, but I think we will soon, and might also want to do something similar with styling different categories.
Is this something WP can do?
