yea, i kinda feel the same way about this, but at the same time you've already got people making things in xsi, modo, zbrush, 3dsmax and posting them here anyway. i mean what's the point in posting your work at a maya site if you're not using maya? i can kinda understand the zbrush postings for texturing, but altering (or building from scratch) your model... i'm kinda iffy about it. sure, there's some talented people that can afford to go and get the 'new fangled' programs and pump out some really good stuff, but in my humble opinion, if it's not maya (or a plugin FOR maya) then i'm not really interested. i'm not flaming on anyone, it's just a personal preference - and i know that means i can choose not to comment or not to look, and i take advantage of those options.
