Modern modes of communication:

1 Cell phone
>talk
>text
>voicemail
2 Facebook
>wall
>chat
>comment
3 Twitter
>tweet
>reply
>direct message
4 Myspace
>justkidding
>nooneusesthis
5 AIM (or other instant messenger)
6 Webcam chat (skype, etc)
7 email
8 blog comment (hint hint)
9 snail mail
10 smoke signal
11 letter in a bottle

But nothing beats 12: face to face connection. There's something about seeing real 3 dimensional people, with their flaws and idiosyncrasies, that we desperately desire in order to connect as humans.
