I'm not sure if this is the right place for this topic, but I like VB blogs and want to suggest you the following:
What I see is that you deal with vb-blog as separate product and I don't see anything wrong with that except the visibility of vb-blogs in the index of vb-forums. Why doesn't vb-forums deal with blogs as a forum? .. I mean why blogs doesn't appear as a section of vb-forums in the homeforum? .. so that when any guest or member want to browse all blogs or just take a look to all blogs in the forums … only navigate into that forum and see all blogs sorted by latest updated blog or whatever similar.
