A huge bunch of stuff on top blogs
The current trend of the internet is to have information brought to you, either with RSS feeds or by finding a main hub of information from which to read. New ways of reaching this group have to be used if you want to make your blog widely read. To be seen you need to bring your blog to a place with high visibility. You could be maintaining a top of the line blog that is filled with interesting viewpoints, but if you are not being seen then you are not being read. A submit blog directory has the readers, you have the material, let the submit blog directory create that bridge.
