I have no idea if this is true or not, but just anecdotally I don't know a single person that uses Threads while X still seems pretty ubiquitous, especially for news feeds and sports. Understand the disdain for Musk, but I'm not sure running away from him to the open arms of Zuckerberg and Meta is somehow better.
Threads is potentially a really nice microblogging system, but they really need to have better moderation and they need to up the limit of characters per post to 1,000 characters.
