Cache / bug?

Some people have noticed that when feeds are updated, they're not immediately reflected in the grazr panel. This is actually a kind of pseudo bug. To speed up people's grazr panels, the grazr server / API caches feeds and opml files for an hour. Changes will be reflected an hour after the first access of a feed or opml file. I'm working on a more 'real time' system for feed updating that should be ready within a week or so, but now I'm still fighting character encoding and the occasional XML/error and hang.
