I have been puzzled by this being said about dlang forever and today about HN. These sites are certainly not noticeably slow, but I don't notice anything remarkably fast about them either. Am I not visiting enough of the slow sites ?

My working hypothesis is that I don't have a good understanding of web-development to appreciate the nuances. Much akin to me listening to Indian classical music, Jazz: I would often encounter trained listeners breaking out into a (silent) applause. At those instances I feel bad because I realize I have missed something but I wish I didn't. So all pointers appreciated.
