I may be in the minority but I would rather stick with a standard forum system. Not a fan of these reddit, lightweight - limited functionality - websites. I see it as more a matter of spending money to attract new people to the forum and marketplace (also improving quality). Not sure how you would do that - although a blog and forum experts offering advice to new freelancers would certainly be a start.

I can kind of see Dan's point though. Even DigitalPoint forums are filled with spam despite the fact they are still a lot more active than here. I first came to forums to learn when I was just starting. Now it seems there are better ways to learn and there are not many people with more experience than myself who are willing to offer advice on forums (not saying I'm an expert but it seems once people learn the basics they leave the community behind).
