Plurk.

I've completely lost the talent for making friends in world if I don't know them on plurk first, and that's pretty bad.

aliciachenaux: LOL! I was just going to say, Plurk, too!

I meet a lot through other friends and sometimes, I talk to strangers when I am exploring the grid who go on to become my friends.

LOL seems like most of my friends' friends are from plurk as well. Clearly I'm not doing it right!
