Due to some technical problems, I have stopped automatic feed updates. I now run the feed updates about once a day so I can keep an eye on how they go. Obviously, this makes the aggreagator a lot less useful. I'm sorry about that.
Although I hate to make my users wait, I can promise relief from this in the near future. Frassle alpha 8 is coming this weekend, with a totally redesigned aggregator. That means frontend and backend. It will sport a whole new interface, similar to Bloglines but a bit simpler, and support new features such as OPML import and feed autodiscovery. Though the interface will be more powerful, it will also show up in your browser much faster than the current one thanks to optimized database queries. The backend will be smart enough to find an RSS feed on most blogs that actually have one, and scalable enough to keep a few thousand feeds updated.
Here's a picture of the new aggregator interface. Click to enlarge:
Thanks for your patience as I hammer out this new version.
