To build Hive yes, if people have those outside accounts then yes that is one method and way to go. As for myself, I do not have any external accounts in social media other than those from and derived from steem block chain. I was out of the social side of the internet for a very very long time.

My wife brought me over to steem, and thus began my foray back into the social side of the internet. I have had people say I should join twitter to promote Hive, sorry not going to happen, I had a twitter account, I used it for less than a week. I did not like it when it was brand new, I still do not like it.

I tried facebook, I did not like it when it was new, and I still do not like it, and will not join it, and when I get that giant we are going to block your view of this business site unless you log in or create an account I exit and travel elsewhere.

I look at random youtube videos, I have not logged into YT and mostly just watch the video, I have no engagement with Any of the videos I watch. No thumbs up, no thumbs down, no comments of either nice or shit, I simply do not care about any of the content providers.

Most of my post are non-hive related, I do advertise on a lot of them for hive on board, just in case someone somewhere miraculously find my post. I also have a tendency every now and then to help a new user, so that is part of my posting. I am not sure I will ever get to the point that I don't make an occasional Hive-centric post, but that's okay, the Hive Post are okay, and the cheer-leading post are okay, they help the new users.

Kind of like your post here, every now and then they are needed for internal and the "oh wow look what I found in this dark corner of the internet" search finders.
