Amusingly, when Joel writes his version of Sam Gentile's It's The Runtime Stupid, Sam calls Joel clueless in Colorado. The central point of both essays is that, as Sam previously put it, is that The languages are just synatatic sugar.
What I find facinating is looking at the places where this assertion is not true. Things like column major ordering or multiple inheritance or dynamic language support or zero based arrays or... but I digress.
Back to Joel's real point. If programming to a browser, what matters most is not whether the programming language is based on semicolons or indentation, but access to the browser's DOM. I agree.
