Sorry but no. I don't care what inflated numbers Meta brags about after redirecting random people from Instagram and counting that as an "active user", Threads is so utterly irrelevant that I literally forget it exists for months at a time because nobody talks about it.
Even here on HN, searching for links to threads.com in comments from the past year yields a mere 53 results. For comparison, searching for xcancel.com, an unofficial frontend for x.com that allows logged out users to view replies, yields 795 results.
Threads is extremely ‘normie-coded,’ I don’t think there’s much overlap with HN demographics.
Twitter seems to be more popular in reddit too

There's not much overlap with any demographics.
