Maintaining a site like this takes a lot of effort. After successfully having outsourced pinging external sites to the Ping-o-Matic, and using Flickr to host my photo's, I decided to start using the FeedBurner service for making sure that all aggregators get up-to-date information.
Just as with the pings and photo's, the reason is that FeedBurner offers additional advantages (statistics, feed optimization, Flickr integration, ...) that I am currently unable to supply myself.
I will redirect request for my old feeds to the new location: http://feeds.feedburner.com/braintags.
[Update 2005.02.02]: Besides moving my feeds to FeedBurner, I also combined all my feeds to a single feed.
