It’s great and detailed explanation, i really like it (I sent it to my CM). As for my opinion, I would say i’m doing similar.
So with LF we focus now on facebook and instagram and for now facebook is getting us a lot of trafic, instagram is for me problem to measure since i can’t put link in comment, so need to find a way to measure and then update you guys
As for linkedin, medium and pinterest - I want to test it out, but have feeling that blog post explained how it goes, so i expect similar result.
What is also interesting for Balkan region is meetup.com, since on Balkans it’s not that used, it’s kind of good hack to use since they(automatic meetup promo mails) will send promotional emails constantly because there are not many meetups in region, so its kind of free marketing + people that use meetup platform are tech savy people so it’s win win. for us, we grew organically there on almost 100 people, used it for last meetup, and 60 people came.
