There are essential differences between two types of pua projects:
One type is the hot topic that can pivot immediately to another track, and in one cycle, it can pivot more than ten times. There are many such projects, and I won't list them;
The other type is to stubbornly stick to one track for one cycle or even several cycles without wavering. Examples of stubbornly sticking to one cycle include @build_on_bob, @LC, etc.; examples of stubbornly sticking for several cycles include @aztecnetwork, @zerion, etc.
The former actively pua users, while the latter actively pua themselves and passively pua users.
