yah, i can see your point (and i tend to be hyperbolic). adding additional categories is fine (and very natural because all of us like things to be neatly labelled and sorted)
the only fear i have in additional categories is that they can be used to say "these people are good" and "there are bad" (probably due to my familial history)
it's easy to think of a grid as good if they contribute code back to OpenSim, like both InWorldz and Kitely has done
but if Kitely or InWorldz were not being successful in making money, they would likely not contribute code. BUT, they also need to have some unique offerings in order to be successful
so i'll rephrase it to "InWorldz has massively been important to me" =)
thanks for making me engage my brain and look a little more deeply at my perspective MetaGirl =)
