I am a Twitter guy with a roll-over presence on IG that I have not utilized. With nearly 8k followers on IG I have done nearly nothing with it since it's creation two or three years ago. So yesterday, after a year of idleness, I posted 12 pics in a row (within 1hr) theme related. In turn net lost of 17 follows. Did I blow up followers feed? What are you IG best posting practices? How useful are hashtags? How many pics per day?
