Right now we have ability to post links and discussions. I propose a new type of post: A request.
A request has a bounty attached to it (provided by the OP). The request itself could be a simple question or whatever the OP deems fit.
Similar to stackoverflow, the OP could accept an answer (green checkmark ✔️), which awards the bounty to the poster who provided the answer.
Requests could be flagged as such, by appending [request: 10000 sats] to the title.
Might need to separate requests from normal posts in the overview. Or not. I'll leave that one up to @k00b ;)
