I have a slight issue with the RSS-feed for remix feedback (comments, reviews). It's quite simple. When I view the RSS-feed, the items are out of order. The reviews always appear as written "yesterday". The comments/smileys then appear in chronologically descending order (the oldest ones at the top, the latest at the bottom). So when I notice that the feed displayed a new item, I have to scroll all the way down through hundreds of comments. This may not be a problem on a computer, but it's a bit annoying on a phone.
Otherwise I think it's a very handy feed!
Edit; I should mention that I've tried several places to view the feed. I had these troubles in Google Reader, and on the apps I've tested.
