Jamie jwz Zawinski has pretty much reached tagging nirvana, I think. His tags are generic enough to be reusable, without being banal.
If anything's not perfect, it's that there's lot of overlap among certain tags -- meaning just about everything that's tagged with one thing is also tagged with another. (I know that this is not actually a problem, but still, it makes me squirm. Maybe I just want a name for it, is all.)
Anyway, I ripped off "doomed". It's perfect for everything from software development, to the end of cheap oil, to, uh, software development.
And speaking of which, let's vow to never forget how fortunate we are to be here squirming over computational ontology, instead of digging our families out of an earthquake in Pakistan. More on that tomorrow.
