The FeedLounge guys released alpha 5, which felt fast to me at home yesterday. It’s positively snappy, though, here on my work machine, which is fast enough to see actual results. Given the speed improvements and the increased metadata mined out of the feed information … I’m very happy with the changes.
Oh, and autodiscovery’s finally supported. [I know why it wasn't, but man ... phew. This makes my life easier.]
