As you might know already that we still have :
Facebook
Twitter
Instagram
Which is mainly used to influence the price also, look at Elon Musk. Honestly speaking I did not know about this platform for real. Right now I do think that this might not be that drastic as you think. We have many more options and at the same time people tend to have a lot of social media platforms in their Mobile phones, therefore if there is a problem with one, there is no reason to rush. At the same time there are community platforms like :
Bitcointalk !!
Therefore the people who are really involved can very easily come and join them, they will not only get all the gossip but at the same time all the information too. Therefore it might be more positive for them.
