haha, i disagree with both of you. i don't think asp is necesarilly a big option for most people. i'd say easily the biggest is php, no argument there. although i'd never use php. i don't think the average, just-for-fun developer would choose to go with asp because mono sucks and windows servers are expensive. the most practical choice is something that will work just fine on a typical linux server.
please, dont call python a scripting language. it's most definitely not. i won't defend php there because i think it's the epitomy of shit.
