I feel like there's a pretty strong delineation between major internet places and what their primary purpose is, so it's always weird to see people wildly breaking my internal, made-up rules. 
  • Facebook is for posting pictures of your family vacations, pets, and kids.
  • Twitter is for anonymous shitposting.
  • Reddit is for connecting with other nerds who share your weird hobbies and opinions.
  • Instagram is for posting pictures of your workout, your coffee, or your ass.
  • LinkedIn is for following your employer's social media to appear engaged.
What's weird is when people shitpost on Facebook or LinkedIn using their actual names.  Or when people post an entire blog entry on Twitter one sentence at a time.  It's like watching a monkey use a typewriter.  Like, yeah you can do that, but that's absolutely not what it's for. #technology
