I would definitely not read that from the data. I don’t know what percentage of current seekers post in the wants-to-be-hired thread, but as a potentially-outlying anecdote, I didn’t until I had already been looking for three months.
I would hypothesize that there’s a psychological barrier to posting in WWTBH, even if you’ve been laid off and have no current employer you wouldn’t want seeing it – there’s a certain vulnerability in putting yourself out there versus privately applying to jobs. For me, it took a certain level of desperation with my search to make the jump from browsing the hiring thread to finally posting in the other thread this month.
