IT seems to me your definition of "good" and everyone else's is not the
same. You seem to think good means local to you - everyone else who doesn't
have last mile cost considerations (probably a majority of non-AU users)
just want to get their stuff the fastest - hence the fastest-mirror plugin.

I think that's pretty good evidence that for the majority of CentOS users,
that's a good system.

We can't show them to users if we don't know about them. We aren't mind
readers, contrary to popular belief.

There may be a valid point here. I don't help manage the centosX servers, so
I am unaware if they frequently change locations, etc. If they are
relatively static, then perhaps a naming scheme that indicates country or
continent of origin would be useful. But again - I don't think most people
care. If a server half a world away is faster, I'm going to use that one.
