I will also gladly admit that there are a few bad apples in the CPAN basket, but going by Sturgeon's Law ("ninety percent of everything is crud"), I think CPAN is doing pretty well. >> I don't know why you felt it >> necessary to compare CPAN to a collection of amateur scripts like >> Dynamic Drive. > > Because it is.

Individual modules may be out of date, or even flat out ugly, but there's still a world of difference between CPAN and a script kiddy site like Dynamic Drive. -- stefan

Yeah, don't get me wrong. The general quality of Perl scripts is far higher than JS. So, CPAN is certainly a much better repository than Dynamic Drive (if you can even call that site a repository). I was just noting a parallel. > > >> I don't know why you felt it > >> necessary to compare CPAN to a collection of amateur scripts like > >> Dynamic Drive. > > > Because it is.

Now that's a gross exaggeration. When have I written about anything but freebie JS scripts? I think it goes without saying that virtually of those are horrible (and I am hardly alone in that assessment). > Has anybody else ever written > code that meets your approval?
