Since I switched MacMegasite’s RSS feed to FeedBurner, I find that my bandwidth usage has been dramatically reduced. One person has complained about the ads in the feed, though. I’m considering some kind of add-free feed for a paid subscription (which would also remove ads from the main page), but I haven’t figured out how to do it. I would probably require a login for the feed, which some news readers still may not support and there doesn’t seem to be an easy way to do it with Drupal.
