I didn't vote it down, but I imagine it was voted down for laughable incorrectness. GNUStep, while a noble effort, is largely a copy of the pre-OSX-era NeXTSTEP API (although I guess technically it's trying to rebuild Openstep, but it seems the history of these projects is so confusing that NeXTSTEP is used interchangeably because it's so iconic), which is literally a decade behind.

GNUStep is not seem to be, nor does it seem to want to be, an effort like Mono to create an open Mac OS X platform (at least last time I looked at it, which was late. It also can't use some of the finest decisions that Apple and NeXT made (e.g., ".bundle", ".app" and ".framework" paradigms) because the underlying linux platform is hostile to them.

Comparing modern OS X to gnustep as anything more than a historical curiosity shows a degree of ignorance and dismissiveness that borders on flagrant. Even assuming the best in people, most mac developers I know would have a frown forced out of them at such a comparison.

I meant very much like it in terms of compared to other frameworks, not in the mono->.Net kind of way, more like the java and c++ being very much alike because they support object oriented programming with built-in features.

You're totally right, though and I would like to recant my previous posts. Oh well, it is too late. My apologies.
