I was expecting something pretty dramatic when I clicked on the linked "extinction event," but it's just the same thing. I can't get a sense if this is one very frustrated person, or if this is really a worrying trend.

Does anyone here have some background on "deletionists" and what this blogger is generally alleging, rather than this specific and rather trivial example?
