Agree. I've use some of my .biz extensions (I use them for my regular job eg file transfer, extranets) to refer industry people to some of my professional resources and they actually like that extension - think its cool and appropriate.
It's a breath of fresh air, after all the dismal choke of .com experience that many in my industry have had the misfortune to experience first hand.
I don't think many speculators who ride on the surface of real business recognise how bad insinuations of .com has sunk in the mindsets of people. Sure, .com is still the most recognised by the internet public what with Yahoo and Amazon and eBay. Sigh, wonder why the big buck sales have vanished?
