These remote job aggregator sites have been popping up everywhere lately but virtually none of them solve the problem I face routinely - transparent compensation. Companies often post stuff like "competitive pay" or "market rate" but that means nothing. Further, conversation regarding pay with these types of companies usually comes up after an initial screen, a tech screen and maybe a take-home assignment. All that just to find out the job pays $55k? Yeah, no thanks.
If you can create a job board that has pay listed upfront and prominently (nothing cagey like a massive range), then not only would I sign up for the service, I would pay for it. Somewhere in the neighborhood of $10-$20 a month.
