Perhaps the best way to generate discussion and feedback on your cube is to ask specific questions about design issues or choices you are dealing with. It's a lot of work to process somebody's entire list and give useful feedback, but if you break it down into bite-sized chunks people can weigh in on.
The more you give, the more you get.
For example, when Chris said that his mid-range decks were struggling and posted decklists (yes!), we were able to give very useful feedback and card suggestions.
Another route is to explain the design decisions that you've made, and maybe go over a card package or how things fit together. For example:

http://www.channelfireball.com/articles/cube-design-remodeling-part-two/
It doesn't have to be so fleshed out, but the more people know about your cube and what you're trying to achieve, the more then can help. Also, the act of putting things in writing will improve your own design. By forcing myself to write things out logically, I often find designs or card choices that don't really hold up very well. Further, by writing things out, you contribute to the wealth of cube knowledge. I might not be in the market for a specific archetype today, but if you've put in the legwork and have experiences to share, that will get my wheels turning thinking about how I can apply those concepts or card choices to my own cube down someday.
My best feedback has come from me putting my designs out there. People know I run Zombie and Birthing Pod, so that opens up the door for people to suggest great intersection cards like Zombie Cutthroat. Even if the suggestions aren't a perfect match, every idea helps.
