Thanks to the free services provided by BlogStreet, I've added an RSS feed to Cognitive Overflow. To make this all look a little better in aggregators, I've enabled Blogger's title field and added the standard orange XML icon on the left side of the page. [Note: this feed seems to be held in cache for a while, I'm trying to figure out exactly how often it reloads.... more info when I find it.]
...or don't. This service is not really ready for use. I can't figure out how often it updates (if it updates). A friend gave up on the feed saying "it kept reposting all of your messages...fooled my aggregator".
