I've also suggested this, calling it '''Wikipedia Two'' - an encyclopedia supplement where the standard of notability is much relaxed, but which will be different from Wikia by still requiring WP:Verifiability, and NPOV. It would include the lower levels of barely notable articles in Wikipedia, and the upper levels of a good deal of what we do not let in. It would for example include both high schools and elementary schools. It would include college athletes. It would include political candidates. It would include neighborhood businesses, and fire departments. It would include individual asteroids. It would include anyone who had a credited role in a film, or any named character in one--both the ones we currently leave out, and the ones we put in. This should satisfy both the inclusionists and the deletionists. The deletionists will have this material out of Wikipedia, the inclusionists will have it not rejected.
But it would be interesting to see a search option: Do you want to see everything (WP+WP2), or only the notable(W)? Anyone care to guess which people would choose?
