Requested a quote for a simple plumbing job. Only one contractor contacted me (high ball) and no others... then I started receiving cold calls from contractors for unrelated services. Not cool.
The whole model is flawed - encouraging window shopping not sales. Notification system annoying (I don't want to be altered that someone favorited my item... I mean - what use is that? That same flawed reasoning / UX rational is everywhere.
Also seems to breed an environment of creepy, flaky people. Makes Craigslist trade seem like normal folks.
