(As the commenter to whom you replied) I agree with your points and observations, but which social network doesn't devolve to the basest desires of humans — the desire to be liked and appreciated, wanting to show off a perfect side, etc. — after reaching a certain volume of users (and more so after being taken over by a large company that thrives on such content)?

Instagram has been susceptible to the same effects, but as others have mentioned, with a small and curated list of people to follow, it's probably a nicer place to be (compared to other platforms like Facebook, Twitter, etc.) when it comes to online social interactions.
