My ServerFault user name is my real name and when you search certain topics in Google you can easily reach questions that I've asked in the past on ServerFault.

I'm a self employed consultant in subjects which are related to Linux infrastructures and such and there are questions which I'd like to ask on ServerFault that I don't want my customers to be able to find (because they believe I'm an all-knowing guy in the subject). Would it be okay to create another ServerFault account that I use to ask these sensitive questions? Or shall I use a guest user name to ask these questions?
