A Comcast customer in Pittsburgh is not amused that Comcast cares. As Twitter user gpk3, he wrote "Comcast sucks," causing Frank Eliason, Comcast's Customer Outreach manager who keeps tabs on Twitter to respond "Welcome to Twitter. How can I change your perception?" The customer was not amused, accusing Comcast of invading his "personal space." And by "personal space" he seems to mean "messages publicly available to the world on the Internet," causing a few Twitterers to come to Comcast's defense. The person I feel sorry for isn't Eliason, though he has to put up with a lot representing the company. No, it's Comcast shareholders, who are actually surrendering some of their hard-earned monopoly profits to pay someone to use Twitter.
