what unwanted domain names are you sitting on?
petercooper: I'm sitting on tons, but I've given plenty away over the years too, so I don't think of myself as malicious. Nearly all are from project ideas I had but then never followed up on.ajaxday.com*
amonad.com*
cocoainside.com*
detailedlook.com
javascriptinside.com
jotpack.com*
jsinside.com 
pythonflow.com
pythoninside.com
railgrinder.com*
railsteam.com (currently giving this away)
railswebhosting.com
rorhosting.com
rubyonrailswebhosting.com
richlanguage.com
rollwall.com
roted.org*
rotes.org*
rubyandhow.com 
rubypedia.com
rubyweekly.com
scalainside.com*
spacepit.com*
startupfreude.com*
superyay.com*
tipteam.com*
topichub.com*I don't think I'd be willing to unconditionally give/swap away all of these, but I'd say for at least half I would (I've put stars next to those). For example, I consider the Rails Web hosting ones to have value - I just haven't bothered to do anything with them yet. Some of the others I am "squatting", in a sense, in order to prevent competitors infringing on my brand.Sorry for the formatting.. too lazy to fix it, but actually realized it doesn't look too bad as a horizontal list anyways..
