Let's see, my first interest is security tools, my second interest is security tools, and my third interest is security tools. So advertisers, now that you have pigeon holed me, try and sell me something ... oops, I guess uBlock is blocking all your ads. So what's the point of this test ?
<sigh> I am still waiting for the day that all the Mercedes Benz dealerships in town to snail mail me an invitation for a demo. Then I'll know I have 'arrived'. Funny how advertisements have worked their way into our heads to become a measurement of self worth.
