There are so much people blogging now that I started to use an RSS aggregator to check what's new. I then moved all the blog URIs that supplied RSS to another subdirectory in my bookmarks (called favorites in Internet Explorer). After a while I realized that I don't use these bookmarks anymore since I read their blog via the RSS aggregator (I use effnews). I only use blog bookmarks for blogs that don't have RSS (or broken RSS :-) And I think more people are doing it this way.
So, if you have a blog, and you want to stay in people's bookmarks, don't RSS.
