This is really, really vague. Please resubmit a more thought-out version.

An environment? A web platform? Are you asking a question, for an opinion on the idea, which could be good or bad dependent on what it is exactly your trying to say.

I wrote this quickly when I should have been listening to my professor.

I guess I envision it as a site with some supportive app-like properties for simple sketchbooking of ideas to peers.

I want feedback on the idea

How would you do it specifically? That's the important thing.

I work sort of methodically, so Ideas are key to me right now.

I can write code for whatever and if I cant, I got a friend for that.

No, no. I meant what is your specific idea.

The specifics you stated - "based on design", "the constant retooling of objects", "an environment, not a forum" - are extremely vague. You need to know exactly what your plan is, before you'd begin designing.
