Aged domains with PR - Want to put up a blog
I picked up some interesting domains on TDNAM earlier this year. I parked and forgot about them. I checked up on them today and found that I have 4 domains, ranging from creation date of '97 to '01, with PR from 1 to 2. I'd like to make something of these, and think a blog on them built for purposes of promoting misc sites would be a good idea.
But where to go from here...Anyone have any thoughts on this? I just don't know where to start. I can handle setting up the actual software and themes and stuff, but just not sure where to go with content. I have about 7 difference C class ranges on a server of mine that I could use as well.
Just looking for suggestions on what I could put on these. Maybe I could just call the blogs <domain name> and just start posting random stuff on them and see where it goes?
