Stephen,
You are definitely not the oldest person on SteemIt. I have you beat by the better part of a decade.
While not everyone's post is their best post and not everyone's post is the worst post, there is value in consistency.
Your posts are informative and thought provoking. I have gotten more that a few ideas from your posts.

Even though a person may not make a lot on there post, making connections and building one's reputation is important too.

Steem on,
Mike
