This thread (no pun intended) is the first I'm hearing that anyone uses Threads at all. To me, it seemed like after the initial week or so, there was only bots left on Threads, trying to hook people to the person's Instagram, or whatever other place they actually post content at.
Threads is the highest ranked "social" app on the Play Store right now, so a lot of real people must be using it despite appearances. Next down the list is TikTok, then Instagram, Bluesky, Facebook, X (below Bluesky!), and
finally Reddit.
