I’ve always been under the opinion that rss feeds are best viewed through e-mail/news clients. I open and close browser windows all day long, but Thunderbird remains open over 18 hours a day.
For months I’ve been using nntp/rss as a bastardized reader which gave me what I’ve wanted. Today there is something better. Forumzilla is an extension in Thunderbird. It frigging rocks. The only major problems I see is that there is zero control over polling and to add a blog to the list requires you to edit a txt file buried in the profile folder.
