Retaining new accounts on social platforms has always been a big challenge. Nikola Bier, the head of X platform, frankly stated that quickly attracting new users is just the first step; getting them to actually use the platform is the real core challenge.

Why? Because X uses an interest graph mechanism, which doesn't allow it to directly sync your contact circle like traditional apps. As a result, advanced users need years to refine their information flow, while new users enter with a blank slate.

The good news is that over the past six months, X has put a lot of effort into this area, iterating and optimizing almost daily. The goal is clear—help new users discover content they like more quickly and smoothly. It seems this approach is starting to show results. For any platform project, this is worth learning from.
