Threads has announced it has reached the milestone of 150 million active monthly users. The social platform from Facebook and Instagram owner, Meta, was introduced as an alternative to Elon Musk’s X and since its launch in July, it has maintained steady growth. Meta CEO Mark Zuckerberg provided the update during his company’s Q1 earnings call this week, as Threads begins to test a feature to let users auto-archive posts after a set time.
