From Meta:

> We are keeping the volume of ads in Threads intentionally low as we test and learn and therefore expect that delivery to Threads will be low. You will see this reflected in your placement breakdown reporting if your campaign delivers on Threads.

Does anyone use threads?

According to the linked post:

>The Threads community now has over 350 million monthly active users, and we’re also seeing that three out of four profiles on Threads follow at least one business.

Take this with as much salt as you prefer.

Yes, but primarily because people are clicking through from recommendation widgets in their Instagram feed.
