Ah, right, I was thinking 'Steem interface', you suggest using asana.com itself. I don't think any third party app is a solution except maybe for specific working groups that want a way to plan their project, but what I'm thinking about is all the stuff that happens before you form a working group: propose ideas, gather input on the ideas, vote on which proposal works best/should be prioritized...
(Not sure where I said people would want payouts, but it's after 1AM here, I need to go sleep first and will get back to you tomorrow :D)
No worries. Asana can be used to track issues and is effectively a forum that allows a greater degree of information management than steem does - that's all.
