I think the difference between social media sites such as Instagram and Twitter that basically promote brevity, and what has happened to date on STEEM is, just what holds value? So far, the mantra has been, original, honest or genuine, along with quality, whatever that might mean.
A selfie of a young woman with a sunset in the background and a caption that says, "The view from my hotel window," might get a bunch of likes on Instagram, but likes aren't the same as allocating a portion of the reward pool. The question becomes, where's the value? Is that a photo anyone can take, or is there something unique about it that makes it stand out?
The same would go for a quip on Twitter. Someone says something that others find funny, so they retweet and like it. How much would they actually upvote it, though? Provided they had the capability to upvote over $1, would they do it?
What about someone who comes across a meme and shares it? They did nothing but copy the meme from wherever they found it on the internet, then posted it through dMania on STEEM. That's been one of the primary functions of both Twitter and Facebook. Does that have value, when the person posting did not create it, and plucked it from a place where anyone could have found it for free?
So, getting hung up on long winded posts, in my mind, is more than just about throwing a bunch of words down and publishing it. We all know that there's plenty of people who aren't all that good at composing a post or staying on topic. Those kinds of posts shouldn't be rewarded much either, even if they have lots of words.
So, I go back to the question I asked at the top. What holds value? Does time, effort, talent, uniqueness, and originality, or should anything anyone decides to post from their phone be rewarded? I think the answer right now is, something with the qualities I mentioned first are going to win out over convenience of use.
Personally, I don't mind that. I think it elevates what STEEM is. Instead of the dumping ground for everything, like social media has become, there is at least an attempt being made to rise above it. Can STEEM survive like that? I hope so. I also hope some kind of happy medium can be found, where short form can be rewarded because it does hold enough value to enough people. I suspect that will happen for the attributes I described earlier.
This is honestly what I hope will happen in the near future. That people will ditch the whole "high-quality exceptional content" thinking that only encourages veryyyy long blog posts (which usually ends up being unread due to how people are lazy in nature) and start acting like a social media platform instead which will likely entice outside people to join Steem.
I don't think that is the future of Steemit.com. Steemit will likely stay as what it is right now, just a front-end to view the data stored on the Steem Blockchain. Nothing more, nothing less!
The future of Steem will probably rely on DApps.
DApps that show only the contents/posts posted via their platform, then microblogging will start to gain momentum. Kinda like how DTube only shows you videos posted via their platform or how SteepShot only shows you photography posts that were posted on their platform or how you can only see questions/answers here on Musing. All of which can be viewed on Steemit. XD
And if people really want to write articles or real blog posts, then they will rely on other Steem platforms instead that focuses on contents like that.
I have made a habit of following people who generally write shorter blogs because I do find them more engaging and easy to digest. I think that often (in the past anyway - and to some degree on Musing), people often write long winded blogs in the hope that they will get more upvotes. But quantity does not equal quality!
We do live in a fast paced world, and your right that I think it would give us more of a chance against other big sites, as they are generally about short form content. I think that long blogs will always have a place on Steem but they might just become abit more niche
