I have access to a few thousand parked domains.

parking them sounds like a good solution. then check traffic.

 

park them at sedo
and if u could develop some of them that would be great !

 

just curious: what'd you choose and how did your results turn out?

 

get a basic dedicated server, make one proxy - a good one i.e glype with youtube and myspace plugins. point all of the domains to that site then list them on any topsite you find especially proxy.org.

 

If there's any really good ones, list them for sale, perhaps in bundles. Release a list of them all and invite bids, park the rest on sedo. Or take the proxy option, although that's more competition in my market!
