It also helps to use an alias along with a fill alias email account.
For example, my *real* name isn't John Galt....not anywhere close, actually....
If I need a modicum of privacy, I simply use my alias (like I do on forums, when I am not sure who or what may access my info at any given time). I have a corresponding Google account, including all of the features that come with that (all the Labs, a Calendar, Mail, Reader, etc.) and there are (to my knowledge) no real links between this alias and my real name, and I prefer it that way.
However, my phone is integrated with the "real" me, so in that respect, you can also easily come and get me - but if I didn't want to be found, I suppose I wouldn't be running a public business, now would I?
