Until now the app called thread is unusable like there is no search apart from user profiles and also most of the users are redirected from Instagram which is also owned by Meta/Mark so the numbers are too huge with no engagement at all. To keep the members alive they need to make changes as soon as possible or else the threads app will become just another Instagram.
Twitter is also struggling due to multiple factors and Mark took this as opportunity to launch a killer app.
The killer app that we thought would rival Twitter ends up failing. Elon Musk is currently exerting every effort to turn Twitter into a "Everything App."
The attention that Thread drew in a mass number of users, during her early creation, has reduced quite significantly. Many of its users on Instagram have realized that there is nothing remarkable that makes it beat or compete with Twitter. Just within a month, the hype that was given to Thread is far gone and nobody seems to talk about her.
