Threads, Meta’s new social app, reached 100 million users in under a week, setting a new record for fastest growth. However, its quick growth may not guarantee lasting success. While the app benefits from Meta’s large user base and aggressive marketing, early data shows engagement dropping off sharply after the first day. Many users likely joined out of fear of missing out rather than genuine excitement for the app itself. Google+ also grew quickly at first but ultimately failed due to lackluster product and engagement. Joining Threads impulsively may end up like “waking up with a hangover” as the app has not solved Twitter’s problems and still faces issues like privacy concerns.
