On the one hand, we're talking about social norms which neither have, nor require, an excuse.
That said, I find the "I want to see your pictures" statement to be generally without a lot of merit. In general, it's probably actually less work to simply try out someone's suggestion than to dig through some gallery somewhere, guessing about whether or not the person's advice is illustrated in DSC_0294 or, 400 pictures later, in DSC_1279. To my eye, the statement isn't really about whether or not you are checking up on a fellow's suggestion, it's just curiosity, and a desire to pass judgement.
I could, for instance, tell you how to do an enlarger diffusion effect in your favorite photo editing tool, but unless I specifically attached a photo to the description, you'd be pretty much as sea trying to find any samples of the method in my work. If I were to "show you my pictures" you'd get a handful of links to a handful of places which contain a variety of different kinds of things, done over something like a decade. Only a handful of them use "enlarger diffusion." Could you usefully judge what I am doing today from this mess of material? Not really, not as far as I can see.
You could, however, form a judgement of me as a photographer. More precisely, you can form a judgement of how closely my photography hews to your ideas of what constitutes good photography, which leads to, roughly, two outcomes:
1. I'm doing photography pretty much the way you do (i.e. good) in which case I probably have little to offer you.
2. I'm doing photography quite a bit differently from you do (i.e. bad) in which case you're going to dismiss my suggestions, because I am all wrong.
There's probably a narrow gap in which I am doing photography which is pretty much what you like and do, but there's some technique I am using which you have yet to master. May I suggest youtube?
