Going mainly in one direction can seem counterproductive on the surface. What it did was open the door and create demand for something like microblogging, which created opportunities.
I can agree with your thoughts about influencers. I don't see a border between Web 2.0 and Web 3.0 though. Can sense things are changing or moving forward. Putting a label on it doesn't define the movement. Us vs Them stops progress in a sense and causes people to focus on differences, for a moment, as things around them continue to move forward. Not one individual can be in control of that. An example is the evolution of Twitter/X. Musk gets all the credit/takes all the blame. Yet it takes millions embracing those changes on their own for it all to be possible.
I agree that the boundaries between 2.0 and 3.0 are still blurred and unclear, but as we evolve, or move into the mainstream, it will become clearer over time.
There is indeed no CEO, there is no structure, everything is decentralized and the individual is free but takes full responsibility for his actions, which also means blame and, of course, success. Otherwise, we shall see. I think that the big corporations will not like this and that it will be a threat to them. It will go very slowly.
