The MVP we ended-up building is live at http://besperk.com . We got decent enough traction in earlier days. It did face some problems - there were no email notifs at first, then there were just too many of them. We tried hard keeping up with them.
But it just didn't work out. We burned-out and the traffic slowly died. But it wasn't all useless; looking back, it's clear, we did solve some problems. Biggest one of them - UX of online forums.
Now we have 4 options:
1. Open Source the Code. It's sorta amatuer but some people might be interested in using / developing it.
2. Sell hosted forums. Blog owners and other people interested? Will you be interested?
3. Get other interested devs on board (It's sorta too much on one Rails dev) and continue to work in this direction.
4. Sell everything.
Would like to hear from you guys. Ideas from HN always help :)
