I find my own use increasing with time. I use it for things I probably don't even need to just because it's there, it's an option, and it allows me to externalize tasks — anything to ease my descent into monomania. But I know plenty of people that still eschew it entirely on privacy grounds (or even just the embarrassment of talking to a phone or empty room).
