********, I have always said from Day One that you should be charging for classifieds. It weeds out the riff raff. But you're bent on keeping it free so I won't try and beat you over the head with it, LOL!
If the new option helps classifieds stand out, then I'd go for it man. I mean, the same dude(s) and dudettes keep posting the same damn ad to keep there's at the top every day/week. Its annoying. If there was an option to have other people's ads stand out from that kind of crap, that'd be great. I'm sure people would use it.
