I like the serendipity of Hacker News, so I don't want to filter out or in specific topics. But if you filter for quality, I love that. Using machine learning to pick out the "best" items was the subject of a discussion recently:

The author is nice enough to keep that app going here:

It is an opinionated filter, but with ADD I can get caught reading most things on the front page. This guides me to some important links that don't initially seem all that interesting.

I asked the author if he would share his training set, or open source the app, but apparently not. If you can turn that web app into an RSS feed or a digest, that would help.

As for your idea to filter on keywords, you can get that working as an RSS feed using Yahoo Pipes without writing any code.

Interesting. I had not seen that discussion. I'll take a look.
