I've previously referred to Penny Arcade as being enlightened by having an RSS feed. However, the feed has been broken for a while (specifically, since April 22). They seem to be aware, but nothing has been done. Running it through the feed validator reveals a server misconfiguration (most likely having to do with Gzip encoding). Since they're taking their time fixing this, and since
curl has no trouble fetching the feed (probably because it ignores the Gzip header), I've put up a local copy that Bloglines (and other aggregators) should have no trouble reading.
Update on 6/15/2005: Penny Arcade seems to have fixed the problem a couple of days ago, so my local copy of the feed now just redirects to the official location.
