I understand and share the interest in recognizing the role of "The Silicon Valley" not only in the History of Technology but much more than that, its significance in shaping our modern Civilization.
We have to be careful; many more Milestones could well be proposed recognizing things directly related to this one, now and in the next years.
This is a subject that with the multiplying of Milestone Porposals will get complicated: which are the "points of contact" and relations to already approved, existing milestones ?
Perhaps each new proposal might include at least a list mentioning related Milestones. That could also be added by our staff?
