RSS 2.0 and Atom 1.0
I am no web wizard, but from what I understand, this has everything to do with the type of feed that you specify for your blog. There are two main types of feeds: RSS 2.0 and Atom 1.0. If you have a blog at Blogger (as mine is) then the default is set to Atom 1.0, I guess, because it is a more basic form and widely supported. However, it does not appear to support comments. A detailed comparison of RSS 2.0 and Atom 2.0 can be found here.
I have changed the feed type of this blog (as well my CAD blog at www.deelip.com) to RSS 2.0. If you are using a feed reader to keep track of this blog you may have to update the feed address. The feed address is http://feeds.feedburner.com/deelipmenezes
