I just updated my existing blogrolling sidebar by exporting from NetNewsWire into Blogrolling and seriously growing the list on the right sidebar. This now represents just about every site I track and read on a regular basis.
Blogrolling.com, recently bought out by Tucows, has added OPML import and export — that means that you can turn your RSS feed-list into your blogroll and vice-versa. [Boing Boing]
