Well the thing is, my one blog is hand-written so it takes time. Waaaaah! Yeah I know.
I do think I found a solution, though, to make maintaining multiple blogs much easier.
All of my inbound links are from forum sigs and reciprocal link directories, which kinda sucks. Thinking about building several sites on different IPs that will naturally gather links (think adult image hosts) and eventually PR, and then use them myself for outbound linking to boost my own sites.
Would welcome the opportunity to talk shop with anyone else who is making more than me in this arena..
