Just my take but...
Some "big" Twitter accounts have appeared here, many of whom I have followed because their content is interesting and relevant to me.
But seriously, guys, what's the deal with not bothering to follow back? I see folks with multi-K followers and single digit follows. To me that is an abuse of a platform. It's not your personal bilboard.
CoSo has no place for haughty, aloof, elitism. It's a community. Join in, why don't ya?
