What a challenge! It is fun reading through the comments...
On the other hand, Steem and Twitter have different primary purposes but both have the social networking platform. While each of us has our preferences (and sometimes we can not manage or juggle between different platforms for valid reasons), there is also the great opportunity to leverage each platform for the benefit of each too. An example of such is the Twitter hustle that @nathanmars has led to market Steem out to the world.
The option does not have to be an "exclusive or." I think leveraging with "inclusive Steeem or Twitter" will work out great. 😊
