I know Hive.blog and ecency have referral links, so that's doable. I've been looking for nearly a year (since I got to Hive) and haven't found one like this.
Implementation should be fairly easy to program, but it would require a developer some time... based on my limited knowledge of coding, it seems like it should be simple.
As for resources, that's a question I can't answer but would definitely like to see answered, too.
Thank you so much for your contributing comment!
I would definitely support such a proposal and in addition to community crowd funding to cover Dev costs, I was thinking maybe we could also consider something along the lines of creating posts with a Devs account recieving a percentage of any associated posts as a beneficiary to help offset the resources needed.
I look forward to following how this proposal moves forward.
