I have my doubts about how real that Threads traffic is. I don’t think I’ve ever seen an organic link to Threads or a business list a profile, I don’t even know what the icon looks like. Bluesky I am seeing all the time.
Maybe that’s just anecdotal but given how frequently meta tries to trick me into clicking on a Threads link I have my suspicions about all that traffic.
Take a look at the graph I linked. Threads drank Bluesky's milkshake.
