Yes. But I made it clear that all replies to be specific to questions. One word for each question. This thread was meant to be a statistical questionnaire not to comment and discuss things.
But let me comment on your answers...
C# as a language, and you mixed it with the platform. I mean the design and semantics, not the .NET or Mono implementations. Only the LANGUAGE
MFC is not an API. Qt sucks, in my opinion, because it uses non-standard pre-processor directives.
Linux API, sucks!!! yes because it's microscopic compared to Windows.
Linux is dis-functional yes!!! It has not even binary compatible within the same distro...
In the end this is my opinion. and you could answer:
COBOL
Ageia SDK API
CEGUI
Mac OS X
And it's your opinion, we just wanted to find the loser among those categories.
