I like your point of view. I actually didn't think of it like that but you have given me another view. The place where you said.

I think this will divide the community as people will all be speaking in different coins instead of talking about the same thing - a system where you get rewarded by upvotes / downvotes.

I don't really go with you there because just as steemit is there, majority are earning from it but what about the minority? Quoting @surpassinggoogle "everyone has something to offer " but what if one is not good at writing an amazing post or into graphics, do you except sure person to just mop around looking at others making it?No
But if he can venture into other means such as steemhunt then with that he can atleast make something out for himself.
My point is that they haven't stopped developing steemit, rather they are trying to make everyone a winner.
