I'm struggling with the same thing. I never actually thought of making a post with the question, though. It might be a good idea to do it.
I'm probably going to cross post from Hive to Steem, at least until my power down is finished. Afterwards, it will depend on my followers
having followers and friends are a big part of my decision - i don't just want to follow the 'in-crowd' , although i am drawn to the decentralized nature of hive over what seems to be lack of decentralization on steem since the arrival of Justin
