I would say you nailed it.
Did Facebook achieve success by focusing upon MySpace and spamming there? No. It established its own market and users.
People want to bring people to Web 3.0 while pushing everyone to be on Web 2.0. If everyone is there, who will interact with them on Web 3.0.
Well said my friend since the problem is identified, I think bringing web 2.0 personal chatting system will be very helpful in boosting engagement in web 3.0 as it can become a means of Business, small or large to hop on, although I wonder if farming will be avoided, and is it that bad to avoid Implementing this.
Is this valid or is there an optimal way you recommend.
