I thought of your web page when I saw this. I bet a lot of people want to talk to you, but you really don't want to talk to them without some serious controls. Which this could give you, since Google voice has real time call screening and pickup, with a good interface and transcription to deal with the overflow.
I just got my account. Searched on a word and got to choose it. I'll never forget my phone number again.
