There were problems with RSS feed for my blog.

1. Blosxom default RSS generator did not produce publishing date properly so all the aggregators take the time to be the time for importing the feed.
2. Other blogs at medhas, except mine, were getting parsing errors with drupal's aggregator.
3. RSS seems to require HTML escaping which the blosxom default RSS output was not doing.
   
4. Read a bit about RSS vs. Atom and voted for Atom mostly because it is under IETF. Atom also sounded technically superior, although I didn't do much research.
   

Here is my atom feed, the old one will remain.
