I'm not a huge fan of Instagram anymore. It seems to behave more and more like Facebook (a platform I left about 5 or 6 years ago). Between the opaque, mercurial algorithm, and the increasing number of ads, its just not that much fun to use now.
For a small artist like myself it imposes a huge cost of time and energy to figure out what the algorithm is demanding now, and as Facebook is increasingly relying on ad revenue from Instagram, the incentive to hide small businesses (to force them to buy advertising) has to be be part of their calculus as they tweak the algorithm. So small makers like me drift quietly into oblivion.
So, my current feeling about Instagram is: meh..
