I've heard of people buying aged/highpr expired domains, setting up blogs on them, and using it as a personal blog network. has anyone done that here? my questions are: 1. how the hell do you get varying IP's for 50-100 site network? don't you have to sign up to many hosting services to do that? 2. is there a way to automatically install WP and manage multiple sites like this? 3. is this worth the time/money/effort compared to purchasing posts on other private networks? your thoughts are appreciated!
