We've had Comcast for about 18 years. The first few years it would go out for a few minutes during electrical storms, but that hasn't happened for at least ten years.
I've never had any of the problems the DUmbass is describing.
Any time I've had a question or problem, their customer service has been excellent.
My only complaint is the price.
There probably are legitimate problems in some towns, but it's also become fashionable to bitch about Comcast, like Microsoft or WalMart.
