Yeah, that's all well and good, except for the fact that Facebook has reached a critical mass; resistance may not be futile but it's damn hard:
1) I have friends all over the world; literally, on every continent. Is there a better centralized method of communicating with them? Should I send out a broadcast e-mail to all of them every time something noteworthy happens in my life? (Noteworthy actually means noteworthy in my world, I'm not logging check-ins every time I go to the grocery store....)
No. Most of the don't care to know about every bullshit event in your life, even though you might think it's "noteworthy".
2) I have friends that only communicate via Facebook. They won't talk on the phone, they don't text, and they rarely check/answer e-mail.
Your friends are stupid and have given up the relative privacy that those mediums offer. Doesn't mean you should.
3) Ever tried dating in the modern world without Facebook? It's instantly assumed that you're hiding something, which to be fair is frequently the case for people that refuse to share Facebook with would-be mates.
I'm glad I'm not dating now. If they only candidates are so invested in Facebook that I get crossed off the list for not being similarly vapid, it'd be a long dry spell.
4) There's an ever growing list of companies and events that decline to maintain a webpage or otherwise keep it updated. If you want to stay abreast of their developments the only way is via FB or Twitter.
Driven by marketing departments filled with vapid airheads who think that Facebook is the Internet.
Facebook is a necessary evil.
No. It's not.
