But I'm curious. At what point do you think it's more practical to use Facebook to communicate something to someone than a phone call or text? Maybe, I'm just not that social and I figure that many people are like me and don't care about my trivial day to day happenings.
You aren't required to post about your daily happenings. You also don't have to make your facebook profile public, so you can use it strictly to contact people (they can't find you), or keep in touch with a select few. You can block everyone's updates, so you never get a single "how my day is going" status update on your screen, ever. Your facebook experience is entirely up to you.
Personally, I loved when texting and/or calling was much more the social norm. If you have someone's number, obviously calling them or texting them would be perfectly normal. But if you don't have their number, it would be infinitely more "practical", from society's point of view today, for you to look them up on facebook, rather than say look them up in a phonebook and call them. And what if their number isn't listed? Sure, you might have means of getting their contact information, but facebook is the socially accepted "norm" for getting back in touch with someone these days, whether it aughta be that way or not.
Again, I'm not saying you need it. You are obviously living your life just fine without it. I'm just pointing out that it has plenty of useful applications, and people's complaints about it are generally entirely avoidable. Shari has the option of either a) deleting these people as "friends", who she seems to despise so much, or b) hiding updates from them, so she's never bothered. But alas.
Twitter is another largely misunderstood social phenomenon. At it's core, it's terribly stupid; honestly, who gives a shit about how such and such's day is going, or that they are in line at the market? But if you stick strictly to following useful pages, such as
http://twitter.com/USCSportsNow, you will get an update every time an article is posted on USC, if that interests you.
These social media monsters have a TON of bullshit attached, but sifting through it is well worth it when it comes to their usefulness and capabilities.
