I'm a relative newcomer to Facebook. From the start I resolved that I was going to take charge of how my page was organized. After all, it was my page.
Here are some things that I've learned so far:
Every decision can be undone. If I decide to hide something or use/not use a feature, I can always reverse that decision later on.
I spend a lot of time on-line and I've met dozens of people, some of whom will make great friends. Only my memory for names is abysmal. If I don't immediately recognize a name on a friend request, I send them e-mail asking how we know one another. So far, I've sent only one embarrassing e-mail, to a person that I'd exchanged e-mails with the day before. I should have remembered who she was. I didn't and she was most gracious when she tactfully reminded me that, yes, we really did know one another.
You learn some things about your friends you'll wish you didn't know. One of them is that some people, who are lovely, delightful people to talk to over a cup of tea or a meal, are abysmal to have posting on your wall. There are some details of my friends' lives I'm happier not knowing. There are some people about whom I don't need an updated every hour. There are some polls, quizzes, and games that they play that don't interest me in the least.
Chat and private messages add a lot to the Facebook experience. I can keep private messages that are no one's business except me and the recipient.
