I use NoScript & Flashblock because it makes my web experience
better. Pages load more quickly, they flash and blink and play advertising noises less, those intrusive pop-ins often don't work, and every time I go on to somebody else's machine to use the web I wonder how they put up with it all. At the same time, I never miss out on any actual features of the page because it's very easy to deal with turning things on.
I am pretty sure this qualifies as "tech savvy".
Nobody would have to waste my time convincing me to turn on Javascript if so very, very many sites didn't spend so much time using Javascript to degrade their site's experience. Don't bother trying to convince me this isn't the case, I have years of concrete experience proving the opposite. Theoretical arguments about how that might not be true aren't going to fly.
