I think we should all understand and accept several basic principles, including but not limited to:
(1) There is something to be said for dignified tolerance.This website caters to a very large number of people who have all manner of different interests in the vast and multi-faceted world of photography. Some things interest some people more or less than others, and Kevin is doing his best to reflect that with the variety of material from the artistic to the scientific published here. Any one who doesn't get warm and fuzzy over a particular topic, say MTF charts, is free to not read about them.
(2) Insulting other members is against the rules and even if there were no rules, it's common decency not to go there. Unfortunately, decorum in public discourse can't be taken for granted these days, so it's necessary to protect acceptable standards of conversation.
(3) Our unfortunately departed founder built this website on the basis of writings about artistic and scientific aspects of photography that are classic - in the sense that they will not lose their timeliness or utility any time soon. Kevin thought it fitting and useful to bring back a curated number of these articles, of which some will be of more or less interest to different people; this too should be respected as a matter of interest to the membership as a whole and an on-going tribute to our founder, regardless of whether a number of members warm-up to a particular topic or not.
Turning to the particular matter at hand - MTF charts - yes, not everyone's piece of cake, not something to ruminate about in the field making photos, but definitely very useful when deciding what lens to buy. A time and place for everything.
