I guess it depends in part on why you take pictures, in my opinion.
Do you take pictures for yourself? Purely for your enjoyment, and expression of your personal vision? If so, then you could not care less if anyone else likes your photos.
Do you take pictures that only other photographers (or critics) can appreciate? Anyone without the same "level of proficiency" as you or as someone said, without WOW photos, are part of the unwashed masses whose opinions do not matter anyway.
Do you see photos as a means of communication that can be appreciated by everyone, regardless of skill level? If this were the case, then everyone's opinion would be vauable, and could be used to improve your craft. I think most of the iconic images in photography (or art in general) fall under this category.
