I know everybody says this, but man, there are a metric boatload of pretty badly formed RSS feeds out there. I have most of an application written that trawls a blogrolling.com blogroll for RSS feeds and generates a “friends” page from whatever it finds. I even respect “Last-Modified” headers. Unfortunately, everyone kicks out bad RSS. Some people also have pretty flaky RSS autodiscovery bumpf — Atrios, for example, winds up pointing my l’il robot to an RSS feed containing the last few comments on his blog. Weird. I could work around that, though, although it would kind of kill the glorious automation purity I’ve got now.
