Very valid points and the reply made by tarindel is along the lines of what I was thinking. Steemit and steem in it's self is a very geek-central 'thing' and it's going to first be inhabited by the culture which surrounds it but that said, & provided development keeps pushing forward to widen the bridge then I see Steemit taking off in a big way. This thing is still in it's infancy and stuff needs to be figured out and I am confident it will be. I can't say I agree with some of your suggestions as far as the segregation of topics and so-forth but I think ultimately what is going to happen is people will eventually fall into their own niches naturally and we will begin to see a much more broad spectrum of content. I was actually thinking of writing a post on this matter myself very soon and I'm probably going to do it. It was a great post and the points you bring up are very valid. I think all we can do right now is see where it goes and help it along the way as seems to be the overall message of your post from the very beginning.
