Text and email have the advantage of not being time sensitive for the participants whereas the voice call requires both participants being available at the same time. I've always preferred email, text and even IM and now Twitter for that very reason. I can send it whenever it occurs to me or is convenient and get a reply at the convenience of the other party. Plus, time delayed conversations make communicating with people in different timezones MUCH easier than trying to convene via voice or Skype.
I loathe being interrupted by the phone when I'm programming, watching TV, listening to music, standing on the stage at PubCon, or breathing. Don't know when it changed because I used to love chatting on the phone in the 80s when I lived in KC. Maybe it was that I used to know some really interesting and funny people that were a hoot to talk with back then, or maybe it was those clear easy-to-hear landlines. I think the real issue for me today is the choppy voice reception in the SF Bay Area and constantly going "HUH? WHAT? CAN YOU REPEAT THAT?" really kills a good conversation, especially dropped calls, and that doesn't happen with email, text, IM, Twitter, etc.
Text rules, choppy reception drools.
Can you hear me now?
What's idiotic is when you walk up to a group of people standing in a hall all texting away as fast as they can go, with each other no less, when they could just be talking out loud.
That's just nuts to the extreme.
I was just starting to speak at a PubCon session and I heard what sounded like a cell phone. The session moderator confirmed not only was it a cell phone, but my ass was ringing. Thought I'd turned off my phone, guess not. So I tell the sleepy crowd "Pardon me, but my ass is ringing" and answer it. Turns out it was my daughter wishing me Happy Birthday a week early because of an erroneous date on Facebook. Wouldn't you think MY kid should've known my own damn b'day? Crowd was quite amused and now wide awake for my presentation thanks to Facebook and my daughter.
