Maybe it's just laziness on my part, but I do find Yahoo!'s homepage to be a good central resource to visit throughout the day. The news headlines at the top keep me up-to-date when I don't have CNN International on the TV (or if I'm on campus and I don't have ready access to TV), the Sports section does a reasonable job of keeping me on track with all the news and scores from my favourite teams, and about once every week I find myself needing to use another of their services like Yahoo! Maps.
That being said, there are two sections on the Yahoo! homepage that I wish I didn't have to see: the entertainment news block and the "Yahoo! Buzz" section. The entertainment news just further depresses me about the priorities of the average American, and the Buzz section is poorly written and seems to serve no other purpose than to promote Yahoo!'s search engine, which I hardly ever use when Google's engine yields far better results for nearly everything I put into it.
You'd think that Yahoo! would offer up a way to let people customize their homepage so they don't have to deal with the blocks that they don't want to deal with. It can't be that difficult, right?
