Voted for Self-search/self discovery.

Just like I said in this comment:
"I randomly found Steemit.
I searched for something on the Google, I clicked on a Steemit blog post.
I didn't even realized this at first, only later, after I read the post, and saw the dollar sign under the post. I started to read about Steemit, I became interested, and I registered on Steemit. This was on 2017.05.17.
As far as I remember, the blog post was some kind of cryptocurrency mining and/or GPU related thing."
