I think this idea has promise.

Shouldn't the "Apply as an expert" really be "What are you expert at and what would you trade for it?" Otherwise how does the matching happen?

I applied as an expert in marketing and music and I would like to trade that for software design/development expertise. But the form seems to focus on only the former, not the latter.

The idea is you help anyone that needs your expertise, and in return you can chat with anyone that can answer your questions. They will probably not be the same people.

So you don't need to tell them what you want in return, but at some point they would need to list all experts they have on file so you can ask to chat with one.
