CNBC and my comment spam

1. Several comments and e-mails express wonder as to why I would watch CNBC. Because of my business, it is helpful to have the TV on for commentary about the stock market, the economy, etc. Every once in a while I glean something useful. Unfortunately, CNBC seems to stray from the financial more often lately and the news coverage is horrible.

2. Anyone know what I can do about the comment spam?
