The first blog post was uneducated and old arguments. Of course you can make 1.7 oz burgers, but only the best can do that with .NET.
But this blog post is just rambling... Why isn't .NET used? Non-techies making technical decisions, or they're hipsters and want to join the PHP or Ruby pain train.
The fact is, .NET can allow you to develop faster than anything else, so these folks are casting about for excuses.
The alternative? Try CodeIgniter for PHP... that's a decent framework!
The only thing more stupid than the internet comments on Hacker News is Google itself: the kings of know-it-all dumbasses!
