Reddit's site is ugly and the UI is horrible. I've tried to use it and it sucks. Plus there is so much childish crap on there. I remember first finding Digg in 2005, then they opened it up to non-tech categories. It was still good, because I could get the feeds for categories I liked. They added images and pics, and I filtered that crap out as well. Then v4 happened and use went down and the categories went very narrow and it sucked.

I really wish Hacker News had categories, but it would very hard to categorize things. Right now I have a massive filter on Yahoo Pipes, but of its no where near perfect. All I can work with is the title of the story to filter things and link.
