What would you do if you had 50 wordpress accounts?

​As title! What would you do? How would you monetize them?
Open to any ideas guys.

Put unique content, related videos and pictures on each and use them as tier 1 web 2.0's?

Build them niche specific as unique and high quality web blogs, age them, point tier 2 links at them, and try selling posts perhaps?

You would probably have had to build them from separate IPs and use different web 2.0 sites as well though.
