I considered EventMachine and Twisted and decided to go with Node. 90% of the requests to the server will be "take this and push it to redis". Another factor in the decision was the other programmer on the project doesn't know Ruby or Python. Another factor was that I'm young, not constrained, and I want to learn everything I can get my hands on.
Sure, that all sounds great. I'm not trying to say you made a bad decision. You're original comment, though, came off as overly forceful, and a mild-bit condescending to the erlang community for no apparent reason and I decided to put my 2 cents in about it. There's no reason why your exact service couldn't be written in another language other than pure personal preference. And thats fine but you need to loosen up a bit about it.
I have more bad things to say about Node :) There are just not enough Erlang hackers around here to consider it, same for Haskell. Even Ruby isn't wildly used around here.
