Well, I suppose before one goes on a rant about people who don't "get" social media the ranter should understand what "social media" is, no?
Social media is not everything on the web. It's typically Web 2.0 sites which are known for there interactive and collaborative nature, and most importantly, to give the poster a reward - a like, a follower, a mayor of, etc.
Forums, like this one, do not fall into that category. They have been around in some form since before the Web or even the dial-up services (CompuServe, AOL) before the web. Maybe the term BBS rings a bell, maybe not.
Also there is a difference, I think, between, posting ideas on forums and posting personal details and "checking in". I don't feel the need to know where my friends are every moment of the day or to get a alert every time they post a blase picture, or they have some obtuse thought they must share with all their followers. That is the heart of social, not mere commenting.
Next to not "getting" social media, I don't get people, like you, who get upset by people who don't fully appreciate their hobbies. By your comment you appear to be an avid fan of the social. Hey, I have no problem with that. All my nieces and nephews in college and HS are on FB b/c it's needed for an actual social life with flesh and blood people, not avatars. I get that. It's not for me. I never said it's not for everyone - that is why I said I don't get it, as in, maybe I'm the wrong person to analyze Apple getting deeper into social.
