Running Multiple Blogs

Is hard man. I can hardly keep up. I have to look at each blog to remember which on I updated most recently. I'm trying to keep a schedule of 3 posts per week per blog. But it gets confusing. As soon as this blog is 90 days old, I can get rid of my other blogger blog and just concentrate on two blogs. I'm thinking of purchasing another domain name and letting blogger host it. I'm not sure yet. Just a thought.
