I'm personally a big fan of trading although It's uncommon and I don't know why. If I have a domain that most would call "Liquid" at $xxx-$xxxx, and you have a few domains that aren't "liquid" (or vice-versa) but they interest me personally and I'd pay a sum equal to the value of my domain, why not? I think it's fair and creates room for possibilities.
I'm always up for trades, so if anyone is interested, PM me.
