I joined as a result of an invitation which I only thereafter learned was my biggest mistake. Somehow, when giving their profile, one doesn't realize by answering an innocuous question, you give them full access to your e-mail.
By social networking I guess I should qualify that. I'm talking about outfits such as LinkedIn and yes, I know folks who have been burned on Facebook.
If that's your cup of tea then that's fine. My only suggestion to all is that you practice "due diligence." While I thought I had, I hadn't and am now paying the price.
C'est la guerre!
