To followup from my blog post about the OSCON aggregator that we're providing:
So you want to follow what's going on at OSCON but you don't get RSS and you don't understand RSS search engines? No probs, just bookmark the Event Blogging OSCON aggregator.
OK, maybe you do get RSS but you are too lazy to do the subscription to PubSub, Feedster, flickr, etc for OSCON. No problem, just subscribe to the Event Blogging OSCON aggregator RSS feed which is a blended or composite feed i.e. a feed of feeds i.e. the OSCON feeds for flickr, del.icio.us, PubSub, Technorati, Feedster, etc. all combined into one feed. The best of both worlds: all possible through the coolness of Drupal (RSS remixing for everybody!) and Bryght!
