I think people focus on people and not the content so much. We both have years of experience in this environment here. Bland and generic information never does well. One can write the best 'article', spend hours working on it, but if the author hasn't worked toward building a following of people who are interested in the author, the post goes nowhere.
I've noticed people tend to follow personalities. They follow the artist rather than the art. The follow the photographer rather than the photo. I could start a new account, only post images, never say anything, and I already know I won't get far.
Some people like rap music. Now think. Do they like all rap, or just specific rappers? Same with any music genre. It boils down the artist, not the art. That personality has more to do with the success than the actual 'product'.
I enjoy moto-vlogs on Youtube. Not everyone would see value in that type of content but that doesn't matter, it's what I like. And course I don't like all moto-vlogs. If the one talking is dull and boring, I'm not going to enjoy that moto-vlog, even though I like moto-vlogs.
Someone here could write the best post about trees. I can't follow a tree though. As soon as they add their personality into that post about trees, then it becomes a unique experience about someone who might be interesting. Often I see people here grumbling about the fact they worked so hard on their post and how their post is perfect, better than everything else. For starters that's a bad attitude, then I go visit and it's generic information I could have googled. So what if it's well written. That's only a small part of what might make something appealing to other people.
