Tim - Thanks for pounding the drum. I've been wanting to jump earlier, when your multiple high-value posts were encountering delivery issues, to provide you with a word of encouragement. I agree with your assessment that AppEngine is a game-changer with teething issues. What I would like to add is that the main problem with Appengine is not technological, but organizational. It suffers from the age-old Achilles heel of thousands of Great Technologies: the mistaken belief that all problems are Technical issues, not People issues.
Why do inferior technologies sometimes succeed while superior ones fail? Often, because the winning technology has people who answer the phone. Is Amazon a technology company or a customer service company? I am writing this to be construed as constructive criticism, because I need Appengine to succeed, because I placed my bet on Appengine. Please, Appengine managers: realize that your product offering is deficient in the customer-service aspect, and that this is a critical deficiency which can lead to ultimate failure. johnP On Nov 30, 7:36 am, Tim Hoffman <zutes...@gmail.com> wrote: > Hi Nick > > Awesome!
