I would like the option to add blogs based on themes and project that have nothing to do with a my personal blog. It would be nice to have all those blog feed into one blog and be able to have specific themed blogs at different location. For example, If I create a community site for my town it would be nice to have that blog on that community web site as well as listed on my personal blog? I guess similar to what techcrunch does.
WordPress 3.0, hands-down. Easy to install multiple blogs in one platform, each entirely independent of the others (including themes).<p>Domain mapping: <a href="http://ocaoimh.ie/?p=89495930" rel="nofollow">http://ocaoimh.ie/?p=89495930</a><p>Getting started with 3.0 multi-site: <a href="http://weblogtoolscollection.com/archives/2010/06/02/wordpress-3-multisite/" rel="nofollow">http://weblogtoolscollection.com/archives/2010/06/02/wordpre...</a><p>Another multi-site tutorial, perhaps slightly out of date: <a href="http://ottopress.com/2010/wordpress-3-0-multisite-domain-mapping-tutorial/" rel="nofollow">http://ottopress.com/2010/wordpress-3-0-multisite-domain-map...</a><p>It's easier these days thanks to 3.0's built-in multi-site support.<p>Hope this is helpful.
I'd have to go with Posterous. There's a menu on the side of the front page where you can easily alternate among your blogs. Easily editable settings, no need for tuts to figure anything out.
