The first incarnation of the proposal withered, whimpering in a corner clutching at napkins in trying to fashion a new hairpiece, and eventually died off through lack of attention and promotion.
This fresh and new vision of the same old thing is trying to restrike the thunder with lightning applause and hopefully will do a better job of not dying than the first.
This is all so that an Area 51 site has the best chance of survival and isn't dragged through gravel and smallpox on account of a previously floated sinker.
Feel free to re-create the proposal if you have reason to believe it will do better this time around. Situations change and people come across new resources and new ideas. But in terms of maintaining Area 51, I wouldn't like to see abandoned or stale proposals cited as a reason to close newer proposals made by people with renewed energy and, possibly, better resources to bring it to commitment.
