Competition, 'in part' should be a big determining factor as to what platform becomes most attractive to 'new' and older members as well.

If Steemit becomes more 'user' friendly and benevolent than previously, under different 'rulers' and Hive continues on in the same way they ran Steemit before leaving, then I would expect more growth within the platform that appears 'less' oppressive and greedy.

My plan, for the moment, is to use 'both' platforms for similar activity, then focus mostly upon the platform which seems 'most' user friendly and appreciative. This goes for any investment in the respective coin/token as well; whether 'on' or 'off' site :>)

It 'also' will determine how I might represent my thoughts about each, to the general public, off-line as well as 'online' through other sources. Negativity spreads like wildfire between people online. One disheartened individual can easily spread bad publicity to ten other people, who in turn spread it to another ten, and on-and-on it goes...till there are hundreds of thousands holding the same view, whether founded or not.
