Just because it's a shiny new technology? Python's got Twisted and Perl has POE if you want to do asynchronous programming. They also both have a very large number of excellent quality libraries to do innumerable other things. I totally agree, it's all about the right tool for the job. Just to clarify, NodeJS is quite a bit different than Twisted and POE because the entire language and its supporting libraries are written for event driven programming from the bottom up. When using Twisted and POE you may end up needing existing libraries that are synchronous, so the wins aren't as great, and things can get...complicated. For a pretty even handed description of this check out Paul Querna's blog post about why Rackspace decided to switch from Twisted to NodeJS for their cloud monitoring dashboard applications [1]. I am not saying Perl and Python are not good tools (they are) just that the benefits of using NodeJS are not all hype. //Ed [1] http://journal.paul.querna.org/articles/2011/12/18/the-switch-python-to-node-js/
