Where's HN and Twitter? :)
(Interestingly, the stats are pretty easy to change. Perl was 2%, then Yuval Kogman and I moved our repositories there, and got it up to 3%. We advertised heavily on IRC, and now it is at 6%. Tripling the amount of code on github in a few weeks is certainly a sign that Perl is not dead. It's also interesting to consider that Yuval and I are 1% of the open source community ;)
Twitter... hrm. Yeah, might add that in the talk section.
HN... I'd feel kind of bad about having an influence on the numbers myself;-)
