Totally agree wrt marketplace. For awhile it was great, the only reason to sign on to Facebook. You could sell anything locally easily and quickly. It really pulled off being a better craigslist which is no easy feat and not something I ever would have thought Facebook would do.
Then maybe a year ago they started focusing on non local/commercial sales and it rapidly degraded to the point where it's not worth using now. It seems like they have diverted all traffic to paid listings so my cheap yardsale-esque deals on stuff I'm trying to get rid of get no views (where a year ago I would get ten messages a day for the same item)
