It's mostly non-recurring memberships because I don't really like subscriptions as a customer myself either, and most people go nomad and actively need the site only for the first few months and then go off on their own, and a subset of those stick around. Which is fine with me. I don't like to create a very addictive product. I think I have a healthy balance of new people and long time members right now.

Ad deals are really hard to predict, usually a VC-funded company (ironically) asks to promote their remote work or nomad related product and they'll pay anywhere from $5k-$30k/mo to promote it on my sites. But those deals can last just a month, to 6 months for example. But ads are not stable income like memberships are for me, so I try not to rely too much on them.
