high reputation of your current message is easy to explain: you have been frontpaged and from some moment you started receiving, at first, some 'blind' upvotes, but, at second, some thoughtfull upvotes also, since auditorium becomes something wider.

Why people dislike your node also easy to explain. Proposing to change somehthing on this site is considered a bad thing in general, and many people downvote even without reading.
However a point of 'not agreeing of introducing some wiki-type shortcuts that will do life of ordinary perlmonks much more easier' I consider as a quite not thoughtful decision.
(sorry for this lenghty hard-to-read sentence, I'm not good with English)

But beware explaining about XP system: it is most veto here, and I do agree that it is really not good to change.
