According to a Business Week article, investors are looking for ways to make some money from the blogging phenomenon. So far, the best bet seems to be software tools that let big businesses build and manage blogs.

Software that trolls blogs looking for useful information also is getting attention. Cymfony, a startup in Newton, Mass., sells software that big companies are using to scan blogs for relevant information. A pharmaceutical company, for example, may want to look through blogs written by doctors, nurses, and patients about a new drug. Customers are paying anywhere from $30,000 to $100,000 for Cymfony’s product.
