FWIW I post in the hiring thread and also review this one for potential candidates. (Found one so far from this month to reach out to, but usually find zero - I think in total we have reached out three times.) We aren't hiring remote-to-start though - if those companies are perusing this thread I could imagine a much higher outreach rate.
I'm not a recruiter (am an engineer) and try to reach out to people that might be good fits. So far I haven't had any that made it to past the initial screen/job-fit that the recruiting team does.
I posted once in the looking and received a couple of calls from that post. Didn't latch on to anyone, but was good conversations.
