Like anything that’s cool and people use to organically connect to one another, companies have rushed into Twittering. To take advantage of this, reader Justin says he’s started following all the companies he gets service from on Twitter. When he saw @dishnetwork tweet about an area getting local HD channels, he asked in reply when Cincinnati would get them. @dishnetwork replied back that Cincinnati should have them and asked for his account for so they could check into it. Turned out he needed a different Dish and the rep agreed to have it installed at no cost instead of the usual $60. “The tech showed up this morning, and I have local HD channels for free,” writes Justin. “I’m finding tracking companies on Twitter is useful because they people monitoring the accounts are ones who can actually do something.”
