RE: Plötzlich "Steemcurator"...
I agree. I had thought about blogging on specific topics with dedicated and targeted accounts - a high keyword density to attract organic search. And then having a "templated" footer to teach users how to join Steemit and join in the discussion.
One of the top articles for Steemit is one about Thomas the Tank Engine so writing about something that will have longevity would be useful too.
SEO was always in important part of web development (as you say, title, h1-h6, etc.) and I used to enjoy the challenge of getting certain keywords to the top of Google's rankings without resorting to "cheating / hidden content". I was pretty good at it.
If we got enough of the good authors together to do this, we could make a significant difference to steemit.com's SEO rank. But it's a monumental effort and I'm not sure I have the appetite for it.
