The Penguin you have used for your Icon is the Linux Mascot, It is used by virtually every distribution. As you may have noticed already Linux users will assume you are a fellow enthusiast when they see it.
I hadn't noticed you over here before, I was probably looking for your HMI Icon. I hadn't realised you were a fellow Linux fanatic but if you would like to start your "Techi Bits" discussion over here I expect we can keep it going. I'll try not to be rude this time!!!
By the way I have a group here on WTR "I'm Refugee from He Must Increase.com"
I would be delighted it you joined.
