I'm going to try this with my Firefox bookmarks. They're already a bloody mess, and I need to get rid of 404ing ones anyway. Except that it'll be Johnny Octal.

I'm going to try this with my Firefox bookmarks. They're already a bloody mess, and I need to get rid of 404ing ones anyway. Except that it'll be Johnny Octal. (reason: https://en.wikipedia.org/wiki/The_Magical_Number_Seven,_Plus_or_Minus_Two https://en.wikipedia.org/wiki/The_Magical_Number_Seven,_Plus... ) This whole discussion of hierarchy vs. tags feels like discussing if hammers are better or worse than screwdrivers, with each people assuming nails or screws out of nowhere. Some things for example organise themselves naturally into hierarchies, such as biological species (both the "old" taxonomy and cladistics are tree-based models.); odds are that the same applies to tags, with some junk out there being specially well suited for tagging. There's also the possibility that different people do work better with one or another. It would be specially useful to identify corner cases where each fails to deliver. Both systems are bound to have flaws; the "right" one is not the perfect one, but the one with the flaws that are easier to address and/or tolerate. A few people mentioned items that could be assigned to multiple nodes as a shortcoming of the hierarchical system, but isn't this rather easy to solve with a disambiguation rule? e.g. for Johnny Decimal, "if an item can be reasonably assigned to two numbers, pick the smaller one." I also don't see much of a problem with synonyms, or in this case links.
