I sympathize with your somewhat jaded view of blue chip galleries, but for those of us who don’t much care about the latest fad, collecting art is still amazing and fun and utterly rewarding. Instagram is a revolutionary tool for artist discovery. There is really good work available at almost any price point. We live in a golden age of artistic creativity, worldwide, and while the big-money end of it can be depressing all the rest of it is just mind-bendingly awesome!
