Feeding the Feeds?

Among the many questions in my brain whose answer eludes me is this: What is up with Bloglines? I will admit to not being the most observant person, but after a while it dawns on me to go check on blogs that haven't been popping up in Bloglines to see if the omission might not be on the blogger's end. Sure enough, there have been at least six blogs who have been merrily updating away under the Bloglines radar. In some cases, unsubscribing to the feed and resubscribing helps; other times, not so much.

Anyone else have this problem? Is there a solution other than resorting to my previous hunt-and-peck approach to blog reading? Because I think I'm too spoiled to go back...
