In the other corner, I have the dozens and dozens of blog posts from HN front page from people who have gotten shafted by Google "support". And those are just the ones who had their ticket escalated, i.e. got lucky and made it to the front page of HN.
I'm not saying you haven't gotten great support. Hell, there are people out there who are happy with Comcast support. I'm just saying I've read too many horror stories to risk our business.
