I'm in the field, so it's worth having a look at Google's new reader. I haven't done more than export my feeds out of BottomFeeder and start importing, but here's my first impression - they really, really need to give the user some kind of feedback during the import process. I sent it over 300 feeds in my OPML file, and all there is for feedback is a text box that says "Your subscriptions are being imported..."
No animation, no progress report. Heck, for all I know it's locked up. I'll have more to say once I see what happens next.
