I'm sure I've bitched about this before, but I'll do it again. Facebook's QA process sucks. I'm astounded at how much crap gets into production there. I know Gonch, Diana and others have complained that the RSS importer to their Notes app was spotty at best, but now I can't even get it to accept the URL for my site's RSS feed. I can't actually make it accept any RSS feed.
And don't even get me started about the quality of the official iPhone app.
You'd think they'd be more careful, what with the assload of ad revenue on the line, and very vocal opposition any time they screw up.
