I have been gradually adding blogs that are somewhat similar but each with a different personality. I imagined having one blog with simultaneous streams. I realized what I really need is one central website so I could have each of my blogs in one central navigation bar. So in the middle of the night I thought of having one WP blog as central to my others with links to each. I decided to use a page for each link. I actually tried changing the url of the pages so that when clicked it would direct directly to that blog. But it is not possible. So my temporary experimental central navigation bar is at http://maaarko.wordpress.com
I would like to suggest that WP developers develop something to fill this need.
