So many people I could have picked. But I am going to start with my friend @ph1102. Here is his latest post (https://ctptalk.com/journal/@ph1102/my-ctp-weekly-report-28-not-too-much-to-show).
He is big into Steem but really big into ctptalk and Clicktrackprofit.
He knows his shit. I make sure I read and learn from hi posts everyday and of course I always upvote, mostly comment and resteem.
If you want to learn a few things about Steem, ctptalk and Clicktrackprofit then this is one man you should follow and read.
