I only posted the job ads that I sold myself. The volume was ok, but not big.
So I thought I'll aggregate remote jobs from traditional job boards. Back then there weren't many aggregators in remote work (maybe two, now tens, maybe hundreds).
Then when that took off way more, I killed Nomad Jobs and redirected it to Remote OK.
I think important is to have a site about a topic that you can then attach a job board too. I did that with Nomad List -> Nomad Jobs -> Remote OK. Product Hunt does that with Angel List Jobs. BetaList with Beta Jobs. If you don't have the topic site, you can't get traction on a job board, unless it's a new niche and you're the only one (like ReactJobs).
Great question! I'm about to sleep so will write more tomorrow.
The validation was 2 ways actually:
