I just deleted a splog on an old domain of mine and started a new project on it (I kept the linktrades on ofcourse). I installed Wordpress Multisite on it and now I'll create a bunch of new blogs and use the root blog as some kind of hub.
Main blog:
http://www.porndiner.com
Sub-blog example:
http://www.porndiner.com/hogtiedbitches/
Reddit will be an important source of incoming links/traffic for this project.
