hi lala, i've been here 2 weeks and used to write on bubblews, but came here like yourself with no following to bring over.
Bubblews was never going to last simply because they where promising more money than they had coming in that's before we even get started on everything else that was wrong with the site . those who knew how google ad's payment work literally just rode that site while we could knowing it was going to crash at some point. TSU was worse I honestly don't know why anyone stuck about after reading the payment structure.
I do think steemit is different though and not just because i got lucky with my first post and made over $200. it's well thought out, it doesn't rely soley on inside traffic thanks to the trading element, they have found a way to make spamming unprofitable very early into the game. and you don't have to be a great writer to earn which will attract content consumers as well as content creators (which none of the other pay per view sites ever managed).
Is the site a guaranteed success of course not but its definitely worth sticking about to find out.
