I understand the feeling that on Facebook there is a community or group for anything or for any geographic group that you can imagine, it is not in vain that it is the most successful social network of its kind.
Personally, I think that each of the platforms that I usually use specializes in something, be it in microblogs such as twitter, photo-blog as instagram, videos on YouTube and so on for each case.
In the case of STEEM I find that the penetration of Steemit for blogs or Dtube for video or applications for audio and other things in this blockchain, do not have enough dissemination or advertising, in addition to some extent I have found one or another complication to share content in them.
I do not complain about steemit, after all I usually use the Steempeak front-end, but if I have a bad experience with Dtube because of the fact that adding videos cannot be compared with the ease with which this task can be performed on Vimeo or Youtube or other platforms.
I really want the popularity of the blockchain steem to increase, not only because of the economic benefit that it can bring to the participants, but also because I really have hope in a decentralized social network model and with a moderation on the part of the users, in addition to provide some degree of reward for the content generated...
