On the front page right now, there are eight programming submissions, and nine web development submissions.
(There is overlap with the programming and web development, but something like usability guidelines fits in web development but not programming. By my definition, anyway.)
* News.YC, which rarely has articles about programming anymore (perhaps one or two a day).
* Programming Reddit, whose commentators think every article is a jab at The One True Idea, which they seem to think is PHP.
* Lambda the Ultimate, which only covers a small area of programming; language design and implementation
I want a site like LtU but with a broader appeal.
