Why is it that _I_ find all the weird edge case bugs?
Here's a fanstastic bug, but what's funny is that it is acting exactly as it should! Newsgator is smart enough to follow HTTP 302 Responses, but when I went to the MVP Summit the Hotel's internal Internet (Lodgenet) was redirecting ALL HTTP GETs to their registration site. Happily following instructions, Newsgator updated my subscriptions and ate my OPML file. Sigh.
Thankfully I had a NewsGator Subscription, and went online to get my server-side copy and I'm back up.
