RE: same articles - I would love a condensed HN RSS feed.

I love hacker news, but the RSS feed needs some work... 118 new items overnight is wearing me out a bit. I built a RSS filter that can filter out keywords from an item title, or limit the feed to a certain number of articles per day. It works great for other sites, but not with hacker news, since I cant see a pubDate (timestamp) tag on any items. But what would REALLY float my boat is an RSS feed with a custom threshold. Could look like this: http://news.ycombinator.com/rss/over?points=75 I'd be happy to offer to do this, but I guess thats not how ycombinator works? It would be cool if we could contribute to the site, though. Out of interest, what determines whether a link ends up in the RSS feed? Is it a point threshold, or is it moderated?
