The different venues definitely have their own "personalities."

My ending up on Steem originally was a response to being totally fed up with the unpleasantness on Facebook around the 2016 US Presidential election and what followed... AND the fact that Steemit (as we called it in the start) had a very similar feeling to social blogging sites from the 1999-2005 (pre-Facebook) era. My choice to become involved had nothing to do with rewards... I just liked the more intelligent and courteous level of interaction, and the relative absence of flamers and trolls.

Except for a dedicated few (often very nerdy) the "message board" format has pretty much died, and that was the nature of my now deceased group.
