This would only be the second year of YAPC::Taipei, and thanks to autrijus we have so many hackers around the world gather at Danshui hacking about perl6(pugs), RT, Kwiki, and SVK.
I've recently add the revspec processing routine into SVK. And just finished a Spork::S5 spork plugin last night.
With all these great hackers around you'll always have lots of ideas to implement, and that's kind of brain-storming you cannot have during normal days.
