While a noble thought, a group thread for chip design will be a clusterfuck of major proportion. Always has been, always will be. Too many cooks spoil the broth, and it's hard enough to get just three people to agree on just a single design-related aspect regarding chips, much less 30 or 300 to agree to complete and total design. My strong advice is just don't do it. Come up with a design privately, and then offer it to the masses. Either they want it, or they don't, and expect multiple people to try and sway your design ideas anyway, regardless if you open them up to debate or not. Any other approach almost always results in chaos, including mixed feelings and resentment from those who participated but did not get their way, or felt their ideas were not given adequate attention. The wide scope of ideas already thrown into the ring in this convo with just a limited number of participants is a perfect example -- group design projects just don't work. Small private groups of three to five people maximum typically works best, and I've even seen groups that tiny fail miserably.
