Cut the guy some slack.. Imagine you just woke up to see Google is now your biggest competitor... I imagine this was written off the cuff and during a state of panic. Entrepreneurship is already a tremendous roller coaster of emotions and this I am sure was not helpful. The founder of LiveNinja doesn't seem immature to me. He built a great product and I am sure very passionate.
Sure, I feel for the guy and I'm sure they are very passionate people, I don't doubt that. But the problem with "off the cuff" on the internet is that lots of people read it and it's not in internet memory. They're running a business and sometimes you need to take the personal touch out of it a little.
What would have been better, from my perspective, would have been after reading the post saying "hey, these guys have a much better product that what Google has launched, it is much more mature and much more thought out. I think I'll give them a try and tell my friends to do the same". Turn a negative into a positive, that's all he can do at this point.
