Some pages should remain stubs. How can one show that? I don't think one can. A short page exists ---> bam! someone affixes a stub warning to it.
The worst thing about wikipedia is nationalists. Also genocide deniers.
The second worst thing is non-notable pages. I think a lot more of them are non-notable than other people do. Then again, I've started at least two pages for people whose notability is not unquestionable: Boris Kornilov and Frederic Wood Jones. But at least they're dead.
