Not at all. In almost all cases, it's a self-maintained illusion that the people that call you cannot wait for a few minutes or hours to hear back from you.
Sure, it might be annoying to someone that they didn't get to talk to you, but rarely does it actually make a difference.
Text messaging wastes far less time, and leaves time for more interesting pursuits than trying to quickly, extemporaneously, condense the purpose of your call into the space allotted by voicemail.
Without my Droid, my conversations would consist of a lot more bookkeeping.
I prefer to treat text messaging like email, where I don't read it as soon as it is received. In fact, using Google Voice, my text messages ARE emails. People get used to and usually respect the fact that I have more important things to do that constantly reply to their queries.
Lately I've been forwarding people that leave me voicemails the Google Voice transcription along with my response. At first, a couple people took offense, but now they're asking me how to set that up for themselves.
