I've been the "go-to" guy among my friends and acquaintances for advice on TVs and home theater, as they all know I'm in to that (or was, a lot more in years past). But I've given up because the same thing happens every time "What TV should I buy?" I ask them carefully about their budget, where it will be placed, what they watch etc, and suggest - without geeking out - possibilities. And inevitably they may as well not have talked to me because they just end up going to Best Buy and picking whatever seems like a good deal on sale.
Many HT geeks have the same experience. People just want convenience, don't want to think too hard about any peripheral concerns they don't care about.
I think people strictly in to high end audio experience less of these questions because far fewer people want to upgrade their stereo vs buying new TVs etc.
