I intentionally use a different name on some websites, just so should anyone google my email name, they'll not get my Facebook details, or my various forum postings. Allows me to do some stuff without having to worry about future employers.
I hear that. I have clients who've found me on MySpace and FB, and have family, so I'm very nice on my FB. The only place I really get honest is LPU, since they won't have access to what I say unless they pay for it. I know THAT won't happen. Haha
