Ah how the rules have changed.
Given that these days one is more likely to make friends on Facebook than at work or at the local coffee shop, we could all use some guidance. So courtesy of Valleywag:
1. Get in the friend zone. Have at least 15 "friends" so you
don't look like a loner. But if you're just starting your career or not
very connected, be wary of filling out with over 100 tenuous
connections; after that, keep it below 300.
2. Be the interesting one. On a network where people actually do stuff (like the social messaging site Twitter),
you can set yourself apart just by never wasting other people's time.
Don't tell everyone "I'm making a sandwich." Tell them "I just dropped
half my sandwich on the floor, peanut-butter side down. I picked out a
couple of hairs so I think it's still okay to eat."
3. Interact with your friends. A Facebook user who just sits
there without messaging, writing on walls, or at least joining a couple
of groups; or a YouTube user who's never left a comment; or a Flickr
user who has just three favorite photos, is like a sex partner who just
lies there.
4. Let it all hang out. The more someone can see of your
profile before they be"friend" you, the more likely they'll see
something that makes you a good "friend."
5. Remember the reality curve. The more activity that happens
on a social site, the more "friends" you can add that aren't actually
friends. For instance, adding a hundred people you've never shaken
hands with on Facebook is bad. Adding a hundred such people on Yahoo
Chess, not bad at all.
6. Fake it just a little. Put up a flattering profile photo
or highlight your best accomplishment. The slight disappointment as
your "friend" gets to know you is a normal part of all human
relationships. Just avoid lies and Photoshop.
7. Don't set your relationship status to "It's complicated."
No one wants friends who are "complicated." Unless, of course, they're
kind of creepy and think they can steal you away from whomever things
are complicated with.
8. Link your social profiles to each other. Link to your
Blogger or MySpace accounts from your Facebook profile. (Unless, of
course, that's where you keep your private confessions and bong
collection photos.) Like adding your friends as "friends" and filling
out your profile, this just fills in context about you and makes you
seem more like a real person.
9. Make mutual "friends." For a particularly tough-to-meet
"friend," you've got to invade from neighboring territories. Yes, this
is a metaphor from Risk, but it's kinda true.
10. Leave a wall post on birthdays. Endorse your colleagues.
Favorite your "friends'" photos. Even if these little gestures feel
meaningless to give, they feel strangely powerful to receive. In
another sense, that's the whole point of being a good "friend."
