I'm posting here an argument I made in a recent AfD, explaining why I think more stringent notability requirements are needed for biographical articles:
"The right point to assess someone's notability and write a definitive article about them is at that point (or sometimes when they retire). Any BLP is only a work in progress until that point is reached. [Some say] "Notability, once attained, does not diminish." That might seem true, but what is being assessed is not the subject's true notability, but a fluctuating 'notability during lifetime' that can wax and wane over time, with the true level of notability not being established until someone's career or life is over. Some people gain awards and recognitions and have long and diverse careers and have glowing obituaries written about them, and pass into the history of the field they worked in. Others have more pedestrian careers.
The point is that it is rarely possible to make an accurate assessment until the right point is reached. What you end up with if you have low standards for allowing articles on BLPs is a huge number of borderline BLPs all across Wikipedia (heavily weighted towards contemporary coverage [...]), the vast majority of the subjects of which will not have prominent (or any) obituaries published about them, and in 50 years time or so the articles will look a bit silly, cobbled together from various scraps and items published during the subject's lifetime, but with no proper, independent assessment of their place in history.
It has been said before, but that is why specialist biographical dictionaries often have as one of their inclusion criteria that someone has to be dead before having an article. I'm not saying we should go that far, but there is a case for many BLPs of saying 'if there is no current published biography, wait until this career/life is over and make an assessment at that point', and until then either delete or have a bland stub."
The above is why I rarely edit BLPs. It is far easier (and more satisfying) to edit about a topic once it is reasonably 'complete', not ongoing. The latter statements applies to more than BLPs (biographies of living people), for example it applies to any 'news' topic, but it does apply especially to BLPs as they are a minefield because they require careful maintenance.
To give some examples of articles I've edited or created that are BLPs:
http://en.wikipedia.org/wiki/Leon_Mestel http://en.wikipedia.org/wiki/Philip_Lieberman http://en.wikipedia.org/wiki/Norman_W._Moore http://en.wikipedia.org/wiki/Robert_E._M._Hedges
Those aren't very good examples. What I'm really looking for is a way to illustrate how some people become notable, and then fade into obscurity, while others maintain notability and accumulate coverage in reliable sources throughout their lives, rather than only briefly. The latter are good topics for encyclopedia articles, but the latter tend not to be. Is there a way to argue for more stringent notability requirements that won't get shot down? Essentially, what I'm saying Wikipedia needs to avoid is bequeathing a lot of stubby articles to future generations of editors who will get stuck trying to find out anything more about people who have faded back into obscurity and for whom it is often difficult to ascertain if they are still living.

We can delete articles whose subject had only ephemeral notability. In such cases nearly the only notable event, viewed in perspective, is that they once had a Wikipedia article.
That is no reason to not have an article while there is public interest in them. We determine notability by information published in generally reliable sources which is not that difficult to ascertain.
