What is PG's so-called "hacker radar" if not some analogue to the "hacker acceptance factor" that I tried to allude to? People think that languages like Python and Ruby are "cooler" somehow than Java - that's all I was trying to get at. I don't think that I was making any judgments about the validity of that opinion, but I would say that it is fairly pervasive for better or for worse, and for many of the reasons that PG alluded to.
