That's the wrong direction: more selective.

The right direction: Wikipedia with a constitutional bias against deletionism. Only false, illegal, or privacy-violating information should be deleted. Everything true should be welcomed.

Sweet! You should start one of those.

I look forward to creating the article "List of random numbers generated by hugh's random number generator on September 18, 2008".

That would be a useless article, but it would be harmless, assuming a sane policy that doesn't allow for terabyte-long articles that strain server resources. Nobody would link to it and nobody would read it, even if your really posted it - which you wouldn't, because you have better things to do.

I look forward to watching it turn into the 4chan wiki.

At some point, an excessive contributor would have to sponsor their own material. It's a business model!

Maybe, although they need to work on the UI. But good start.
