@TechnicalKO I find twitter useful for finding out information, events and follow a very select few and TweetDeck really helps me keep it useful.
Instagram is more for social, family & friends images. I find now though that out of every 4 images, 1 is an advert, 1 is someone posting something I don't care about, 1 is a repeat post from somewhere else and the last might be something I find interesting! I can't see myself leaving though due to the links to friends and family. I did try once!
