Here, I just made this for you: http://feeds.feedburner.com/HNWatrcoolr

It is the last 30 HN stories that made it to the top of the list. If you put it in your RSS reader, you can then visit it each week or whatever to catch up.

I'm getting these from http://hacker.watrcoolr.us (a site I made a few weeks ago).

The feed for that site is http://feeds.feedburner.com/HackerWatrCoolr (though that includes other sources in it as well.)
