I suspect the submitter's interest here was on the unintended consequence of the StackOverflow reputation system, since HN also has a reputation system that it periodically navel-gazes about.
I am not sure this was a very good link, other than to say 'I can write this shorter than you and omit optional variables, oh and karma sucks'. Not a shining example of how cool perl is.
Is there some concentrated effort to promote Perl around here? I've been a regular for years and Perl comes up...well, maybe once every 2 months. The last few week has seen about 1/day.
I agree I very rarely see articles posted here about Perl.
Probably the reason that you have been seeing more Perl posts in general around the net lately is due to the Perl IronMan Challenge which started at YAPC 2009. It's an initiative to promote the language. http://ironman.enlightenedperl.org/
All I was getting that is that Perl is a pretty cool language that runs the risk of becoming an obscure language because progress on it has the appearance of moving so slowly. For whatever it's worth, I don't think that it really is moving all that slowly, but Perl 6 was announced almost a decade ago (2001) and it has all the appearances of being a pretty bureaucratic process. I know there are a ton of really sharp people working on it... just like there are a lot of sharp people working on CL.
Until they get their PR house in order though, I honestly think that Perl will go the way of CL.
