Like Matt, I do not mourn the decline of the phone call:
Personally, I couldn't be more thrilled with the phone's decline. I used to be painfully shy as a person, and while I've largely gotten over that IRL I still find it incredibly stressful to talk to people on the phone.
Instead, I email. I SMS. I blog. I Twitter. I write on Facebook wall pages. I use IM and GChat constantly. Anything but the phone. I'm sure I'm not the only one who feels this way, and in the years to come we phone-haters will inherit the earth. I call it progress.
Weird fact: every single (successful) blogger I know hates talking on the phone. I'm gregarious face to face, and I'm an inveterate user of various kinds of textual messaging, but I would rather scrub my floors with a toothbrush than get on the phone. I don't mind doing interviews, but whenever I make or receive any other kind of phone call, even from charming people whom I deeply love, I immediately start wondering about my exit strategy. One blogger I know won't even check his voicemail. I have no idea what this all means, but it must signify something about the kind of personality it takes to blog.

It's about control, and speed of information uptake. Reading is prefereable to listening because you can consume at whatever rate maxes out your ablity to take in info. Phonecalls disclose their data at whatever leisurely pace the other speaker feels like talking, and they tend to prevent much multitasking. With emails and text messages, you're not subject to the conversational whims of the other person, you can drop them for anything else more pressing, and you can just communicate faster overall.
Bloggers and blog consumers alike--we're just higher bandwidth people. Do you sit down and watch CNN, or do you have it on in the background with a computer on your lap? That's the test
