We've completed a major revamp of our Feeds, particularly those that show All Rankings - By Score and Date. Pretty much, we've sped up the generation by a lot, which is good news for us, but probably transparent to users.
One thing, though, which you might notice, is the removal of the RSS feed for "All Your Rankings". On review, it's clear that it never made sense. I mean, how can you have an RSS feed of films by score? The XML, TXT and HTML feeds remain. Plus, we still offer an RSS feed for your "Recent Rankings", which just spits out your last-ranked films. That's updated hourly.
