"Please don't leave a message after the tone."
This is exactly how I feel:
It takes much longer to listen to a message than read it. And voicemail is usually outside of our typical workflow, making it hard to forward or reply to easily.
I hate voicemail. I especially hate emailing people and having them phone me back instead: "Hi, I got your email and am calling..." Come on.
People like to complain about spam on email, but for me the phone is the ultimate source of unsolicited communication. There are a few people I'll use the phone to talk to, but if it weren't for them, I'd dump the technology completely.
