I never had a MySpace account, but a lot of people told me they all left when they disabled all the groups. Here, changes are voted on, and if most users don't like the propositions, they will correct it since witnesses all want votes. Steemians are already 1 step ahead of the masses who will only use the most popular site all their friends are on. I don't think Steem users will ever all abandon it and move to another site like the sheep sites.
