There's a lot of Wikipedia I think should be more transparent or more approachable. But deletion discussions aren't really one of them. Deciding what really fits in an encyclopedia isn't simple. Wikipedia has spent literally a decade working out a set of rules that balances utility, fairness, quality, and maintainability. Those rules will inevitably seem bureaucratic and opaque to people who haven't worked on a numbe…
You have deliberately ignored the most contentious part of the Wikipedia policy regarding articles, which is the "Notability" rule. Why an Internet-based encyclopedia with no editors, printed version, or quality control feels the need to limit articles to "notable subjects" is beyond me - it isn't like we're going to run out of electrons any time soon. In this particular case, it was quite clear this person existed a…
Let's look at the general notability guideline (WP:GNG):
> If a topic has received significant coverage in reliable sources that are independent of the subject, it is presumed to satisfy the inclusion criteria for a stand-alone article or stand-alone list.
That's it. Simple. Wikipedia wants sources to back up whatever's in the article, it wants significant coverage so it can actually write a decent article using this information, and it wants them to be independent to avoid bias in the source material.
Why it ended up being called "Notability", I don't know. It probably should be renamed - but anything that's sufficiently notable tends to fit this general notability criterion, and vice versa, so I guess it's a decent proxy for notability as well.
