IT House News on January 21, after blocking third-party Twitter clients, Musk tweeted today that he would introduce a "new" feature. In fact, these "new" features are not new, and they have been online for a while, but they have been withdrawn because they are not very effective.

IT House learned that Musk teased the fixed list feature in his tweet and introduced the 3 steps required to enable it. In fact, this feature was launched as early as 2019, but users did not use it frequently, and finally Twitter returned to the normal timeline.
Creating different timeline content based on specific topics sounds great, but Twitter's previous attempts have not been successful. Before Musk's acquisition, Twitter was still using algorithm-based recommendations as the default timeline, rather than chronological order.
