Why don't all the extreme wikipedia inclusionists start their own, more inclusive, wiki? One with a page for every random idea that anybody's six-year-old kid ever has?

I'm serious.

Yeah, hard disk space is cheap. excluding stuff is dumb. if you want visitors to find high quality articles then make the search box work well. google doesn't exclude webpages for lack of notability. their bar is low and they make up for it by knowing which things are more or less notable.

Actually, if you start making pages for every not-particularly-interesting integer on the order of a googolplex, you'll quickly find out that hard disk space isn't cheap any more.
