I'm an extreme Wikipedia inclusionist, but unfortunately that is not the rule on Wikipedia. http://en.wikipedia.org/wiki/Wikipedia:Notability
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.

i think you could make a case to insert it into wikipedia if you can get on that page, and it probably isn't that hard to do if you set your mind to it :)
