As others have said, it’s a very different space to Twitter. It took me a while to figure it out. Coming up for two years now, and I’ve followed interesting people, made new friends, and reacquainted myself with old ones. This is home now.i don’t fret about follower numbers.
I might suggest you just start posting thoughts, comments, links - like that other place - and people will find you. What is it James O'Brien says? Build it and they will come.
