Comcast is pretty good compared to Frontier. People with DSL don’t want to hear you bitch about your cable provider, particularly one that (relative to others) charges a premium price for a premium product.
I'm not completely unsympathetic to people stuck with DSL since I grew up with dial-up and that's still all my parents can get (apart from wireless), but I'm absolutely entitled to and will continue to bitch about Comcast's service when relevant.
