I wrote a report in my freshman year of college on Google+ and how it was going to be "the next big thing in social media" due to Circles and how easy they were to use (I even got A!).
I still wish these had caught on more, or at least that Facebook hadn't implemented Friend Lists as an answer to this that they all but bury in their UI. It would be a much more tolerable place if they made it easier to use this, but similarly, if you have to categorize people in such a way that you rarely see their posts, what is the point of "keeping in touch" via Facebook in the first place? At least for me, if I don't care enough to see your updates (or at least the memes you like) on my news feed I may not think to look at your profile.
