I have been tracking the Consumerist website for a week now and have found that it provides valuable data for business and personal use.
They were one of the first sites to announce Circuit City's planned closure of 155 stores, and they track consumer trends that can effect business. For example the backlash on overpackaging products that will effect the toy industry, rashes caused by baby clothes etc.
Each one of these Consumer issues will effect the industries/ companies financially by lack of sales, litigation or business model changes.
