The deletion of wikipedia articles makes no sense to me and always feels to me like a random editor going on a power trip I routinely try to look something up that I remember had a page 5 years ago but now redirects to some 'list of x' page where instead of having a full article about it, it is just a bullet point with no description. Why delete the article? Definitely not to make the site better...
