I converted this over to beta because I did not foresee anything that I would lose with the conversion. I did find out that I cannot leave comments on blogs that have not converted over to beta. This does not please me since I like leaving positive comments when I have the chance at my favorite blogs to read. I also have no real way of know which blog at Blogger is a beta or not.
It could be worse. It could be like some of the friendster 'free' blogs where you completely cannot control the ads that are on your blog. And, this is one problem in an otherwise problem free blogging experience.
