I have some domains like that... I've thought before that it'd be cool if there were a way to give away (or sell) your domains in a way that would make sure they weren't squandered or squatted. For example, you'd put the sitegarden.com in a sort of escrow, and whoever you gave it to would use it to develop their site. At the end of N months/years, if they had a real and functional site, they'd get the domain name (and optionally pay you something then). If not -- either their app had failed, or they never got it together -- the site would revert back to you, they wouldn't owe you anything, and you could try again with someone else.
