These are good points. However, I think that a few things really differentiate things here.
First, KF would NEVER allow for a thread like this to continue. It would have been locked immediately. By allowing this thread to continue (and others that preceded this thread), it's allowing for people to air out their opinions which, for me, has made me feel more like a part of this community than at KF.
Second, in my experience, the vendors here are much more respectful of each other.
Third, Dave, Jon, Marko, Stefan, and the other vendors, including the knifemakers, all have their niche - they are not competing with each other. Dave and Jon both have sharpening products, but with only nominal overlap. The knives they sell are different. The knives sold by the knifemakers are all different. And specifically with respect to Dave and Jon, because I've spoken with both, neither are openly pushing their products in this forum at the expense of someone else's product or price cutting for the sake of poaching sales from other vendors. This was obvious at KF.
Fourth, and lastly, I think the people here are, all in all, better members. They are more respectful and knowledgeable. The more experienced or long time knife owners here may have strong opinions, but, from what I've seen, they've been offered in a friendly manner.
I've enjoyed being a member here much more than at KF. And I'd like to thank all the members here for a great forum.
