Choose friends wisely
It's considered very rude to delete someone as a Facebook friend. It's more acceptable, when you're on the fence, simply not to accept an invitation
"Poke" carefully
The Facebook "poke" feature means different things to different people and can have a sexual connotation. If you think there's room for misinterpretation, it's safer not to poke at all
Respect your child's privacy
Many grown children are unpleasantly surprised to find their parents now on Facebook asking to be friends, which many consider an invasion of privacy. Instead, consider mentioning you set up an account and letting your child decide whether to become your Facebook friend
Think before posting
A message posted on the "wall" section at the bottom of a profile page can be read by anyone. If it's not appropriate for someone's boss to read, don't post it. If someone posts something questionable on your wall, you can delete it
Post a photo
Photos really help other people connect a name to a face. Plus, nobody likes staring at the default blue question mark used for those who don't post a picture

Forget about privacy
One of the benefits of Facebook is that you have a high degree of control over what people see. For instance, adjust privacy settings if you want to limit who can and cannot see photos of your children—or your cousin's bachelor party
Overdo friend requests
It's easy to upload Gmail and other contacts and automatically issue friend requests to a whole address list. But one recruiter says when he tried to upload 4,600 e-mail addresses, Facebook shut him down for site misuse
Flood your network with status updates
Because your friends will be reading your status updates in their news feeds, it's best to show restraint. If you need to update your status more than once or twice a day, you might want to check out Twitter
Be creepy
You may share the same music interests as that nice 20-year-old, but it doesn't mean she wants to be your friend. It's not a great idea to make friend requests of strangers, especially ones who are significantly younger than you. Even if you know them, it's usually a better idea to wait and let young people take the lead

Avoiding Facebook Faux Pas

Even minor miscues can betray your over-the-hill social status

By Rachael King

Facebook can be a compelling way for the over-35 crowd to keep in touch with friends and family. Still, it's got different rules from sites such as LinkedIn, and it's a whole new way of communicating for a demographic that went through college without cell phones, the Web, and e-mail. If you're pushing 40 on Facebook, you'll probably never qualify as cool, but you can avoid major social-networking taboos. Herewith, Facebook 101 for old folks.
