At least when I was using livejournal I had to learn to use some HTML to make my profile a garish eyesore. Part of me misses that level of customization, but maybe only because I didn't bother with myspace so I didn't see the hell that could become first hand. I find the uniformity of a Facebook or Twitter feed visually a lot more sterile and a lot of that has to do with advertising. My Facebook feed turning increasingly into ads or posts from pages I don't follow has made it more and more difficult to actually use it to keep up with people--which is ostensibly the purpose--but until a decent competitor arises what else is there?
