I've been a professional coder for 14 years if you consider that savvy...

I am constantly finding products that interest me, and have no hesitation of putting my unaliased gmail address into random product sites.

You may be surprised to learn that my inbox is not a cesspool, there is nothing in there which I didn't ask for.

I believe the aversion to spreading email addresses online is actually a holdover emotion from a time when spam was an unaddressed real problem and where obfuscation was possible.

Today, your and my email address are already in hundreds of purchasable lists... and the battle is fought by gmail instead of by me.
