I've discovered a way to subscribe to Blogger's blogs. At a first sight is not referenced in the blogspot accounts.

The trick is so easy and works with the few blogs I've tested: get the URI of the blog and add a atom.xml. For example, for the http://mda-soa.blogspot.com/ blog their syndication URL is http://mda-soa.blogspot.com/atom.xml.

Feeding liferea. It works.
