I emailed one of the Street.com writers and he responded.
The gist of his response was not to take his article personally. He said he likes the XM service, but not the stock. In response to a question as to why so many negative articles on the Street.com, he responded there is simply a lot of interest in the stock.
Take it for what it is worth, very little, actually, but at least he had the decency to respond.
