I've also never had an issue with Facebook. I've been online through usenet/irc, AIM, livejournal, and then forced to join Facebook because everyone at the university was using it for class correspondence. Later, I have exactly your sentiments, that it has allowed me to stay in touch with people I would have lost touch with over the years. I take advantage of some of the groups for my industry, and my hobbies. I use our company's Page to interact with a whole segment of our international customer base, that would never think to call our support telephone number or e-mail. It's never been a negative experience for me. Although I only look at it when I get home from work at night on my desktop computer. And don't ride around all day with the app running in my pocket. I don't quite know if that would make a huge difference though.
