I think owners who interact with thier customers know that it can really stroke our ego if they converse with us. The internet has brought that into being, as a line of communication. This produces fan boys, and I mean that in a good way, not derogatory. If you were able to shake Mr. Tony Bose's hand, or exchange some thoughts about product with Mr. Sal Glesser, you will buy thier product over your lifetime, for yourself, and for friends and family. Imagine giving your grandson a Tony Bose knife and be able to say, "Sonny, when the internet was still around (think obsolete like lp vinyl records), I conversed with Tony, and he was not only really nice, he makes great knives. So, I want to give you one of his knives before you grow all the way up." It creates loyalty being able to meet the maker if you will.
Unfortunately, these guys sometimes get harassed by troll spawn wanting to be a knife know it all. I am glad they have thick skins, and stick around. I am sure the forumites eat them up like pirhanas anyways.
