Companies and individuals edit articles about themselves, if they ARE or ARE NOT donors.
Please explain the logic that says you should not donate to Wikipedia, if you have edited an article about yourself?
OK, just because you edited your own article doesn't mean it's not NPOV. But let's say it was biased in your favor...
So what if the article is not NPOV? Other editors will participate in its development.
Also, if you can't prove your notability beyond a shadow of a doubt, there turn out to be an army of deletionists visiting all the articles who will be more than happy to nominate you for deletion in a few heartbeats.
