[deviant]

I love .net for building webapps, but I don't think that it is practical for most sites that only need smaller amounts of scripting. For that, PHP is king. I've used Ruby and Python for other tasks (security tools, bots, etc), but I would never use either for websites.

I'm not a professional web developer though, more like a hobbyist so I make no claims to absolute wisdom, I just have my preferences I guess.
