I'm not on FB. I also haven't used Instagram for a while. How has Instagram changed in the last few years?
Yep. It annoyed me to no end to learn that I had missed a bunch of images posted by a friend because they were never surfaced to me. It turns out my rampant liking (it's super easy with the double-tapping) of someone who burst-post(s) suddenly made me seem like I was a "fan" of theirs. In reality, I just double-tap everything.
