This one looks interesting. The top project has gotten $7,858.50. Not too shabby. The docs are pretty thin though, so it's not clear if it's possible for devs to attach a price to feature requests themselves. I've been looking for service with a flow like 1. User opens feature request 2. Dev responds with "Not useful to me, so I'll do it for $200. Click this button to pay." Edit: Issuehunt.io seems to be a side project of the people that make Boost Note. That may explain why BoostIO/Boostnote is the most funded project, and why there doesn't seem to be much ongoing effort to promote the service. I get that "we made it for us, but you can use it too" vibe from their site.
