Irrespective of the disruption and competition Steemit has brought into the game, other social media platforms still remain relevant in some quarters.
Facebook is still useful in driving traffic/attention to one's content here. I do post my steem links on LinkedIn as well. They're still very useful.
I've been seeing a couple of "Ditch Facebook Campaigns" here, well, I'm yet to decipher the bases for the campaign, but, in my opinion, I believe other social media sites are still very useful. They compliment each other.
Cheers!
I'm telling you. I still post my links on Facebook and sometimes when I post, people will ask of steemit still pays and I'll say yes
