YouTube added as a pace that far exceeded the others.

It's almost impossible to disrupt Youtube even on the off-chance. A particular social media, over a period of time, also becomes a part of culture. When it comes to subscribers in Youtube, quantitatively it does the job. If it says 1 million subscribers, it also reflects that in true sense. That follower/following base even though present in Web 3.0 it's not being able to translate into a network effect. That is the dfifference between the two.
