People may interpret it like that (phobia, even if in any case I think that would be too strong a term in this case), but personally that is absolutely not what I meant!
I presumed our different views were rather coming from the fact one of us is part of the public for this kind of material, and the other is not, so you see only the theory, while I'm interested in getting a system that works for me practically.
Which, actually, is very significant if we think of your last paragraph: I do totally understand your concerns, and share them. Now, there is a paradox that is not easy to fix: categorizing is unpleasant and possibly counterproductive, but not categorizing can make the material unreachable. Having the material reachable but not categorized on here would be doable with working tags though. I'm not sure why not more effort was put in making the tags work. I don't know of it's deliberate, or a bad design difficult to fix?
