My SF 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 in SF.

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 in SF 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 a secondary SF user name to ask these questions under this account? or shall I use a guest user name to ask these questions?
