"I find that instead of checking Facebook any more, I check my Steemit feed in my spare time and leave a few comments on other’s posts"

Me too - which is why I think centralized forms of Social Media like Facebook are fearful of this disruptive rewards-based platform. Facebook recently stopped accepting Crypto's.. probably in order to launch their own.

Why spend time on Facebook, when you can earn $ for your voice/content you already create?

For new users, I think commenting is where it's at. The one's who have the 'get-rich-quick' mentality will not succeed. At the end of the day, it boils down to educating each other through our various skillsets, knowledge, experiences, etc., people should capitalize on their diversity.

Thanks for the information!
