node.js is another blessing to web-development like django was to me a while back - allowing me to hack interesting things in new ways, with smarter interfaces.<p>but one bonus i notice about node.js is the ability to even do tcp stuff using js and with callbacks! i hadn't done a lot of hobby-stuff with low-level server stuff, but node.js is helping me explore that area now.<p>what do others think? i hadn't used the other comet options available witn python and ruby implementations, but i think node.js leverages existing knowledge of ajax-aware devs.
