I think facebook does marketplace really well. Whenever I listed something it sold, and I'm talking about really trashy stuff like a $20 microwave. I get a lot of noise (weird messages) but haven't seem explicit scams like you see on CL and you can sell the stuff usually within a day.
They also do events pretty well. It's easy to invite people and most people my age have a neglected facebook account so you can usually find who you want to invite. You just have to make sure you don't miss seeing the event.
