I'd never heard of the C10K (http://www.kegel.com/c10k.html) but I love scaling issues and this looks to be some fascinating reading. Thanks!

EDIT Interesting annecdote... Cal Henderson is the author of "Building Scalable Websites" http://www.amazon.com/gp/product/0596102356 and has worked in "the trenches" as the lead engineer of FLICKR and developer at B3TA.

Apparently his newest company http://tinyspeck.com/ is using node.js for their game engine.

Assuming he's planning on scaling to a reasonable size, that seems to be a pretty resounding endorsement that there's at least something going for it. I mean ... that guy's got a bit of experience in working at scale.
