Great points, Fok, and I agree. It seems to me that the thread is largely divided in terms of criteria into two quite different groups: (1) who are more like critics, and (2) who are more like customers. They'll use the same terms (greatest, innovative, etc.) but necessarily have two COMPLETELY different sets of experiences and criteria in mind).
Given that SF isn't, technically, a "fashion" forum in the classic sense (like thefashionspot ca 2003-5), I'd actually say this forum is more heavily populated with "customers" (group 2). For example, how many members here have actually gone into stores, or reviewed collections in person, that they had no intention of actually buying? How many keep up (or kept up) with the industry outside of their "personal" favorites?
So, it's difficult to get many of group (2) understand, for example, why Gaultier or Ferre might be on the list but not Borrelli, because 99% of members have never owned Gaultier or Ferre, and probably never really even seen one. RL, though, is owned by just about everybody here. As well, classic makers like Brioni and such are probably much more represented, because it is a site with a lot of professionals, not just a lot of fashion fans.
Finally, if a discussion like this becomes too "personal aesthetic," then the discussion becomes just like every other thread on SF. "Check out my new XXY suit; isn't it great?" "I don't like the drape." "Well, I like the drape." "Shoulder has too much padding." "I like padding!" etc.
Whether I like Gaultier or not, or whether I wear Arrow shirts, doesn't mean that both of them aren't more influential than, say, Roberto Menichetti... even though personally I wear his stuff and have more of his garments than either of these others. Thus, I'd put myself and my comments into group (1), as I would also Fok's, but many others would be in group (2). I don't know that we'll ever be able to come up with a comparable list, though BOTH are equally valid (in a sense).
In any case, it's still been (and is) a very good discussion and I'm learning a lot, especially in this recent batch.
