Facebook to a lesser extent - that platform is still a useful means to communicate with family who are scattered wide.
By far, I am really enjoying Instagram at the moment - it is SO much more peaceful and non-confrontational. I only have a tiny couple of hundred followers, and am following about the same number of friends, musicians, guitar makers, tea manufacturers and such. It is just nice to sit back and scroll through my feed and see uplifting images with NO arguments or one upmanship or sniping going on...
