This week's cool tool is not a software app, but a website. . .

I recently joined Revenews.com, a website that provides marketers with news, advice and analysis. The site covers such topics as affiliate marketing, online marketing, online publishing, search engine marketing, and PPC.

I subscribed to several of their free daily newsletters. Though I get way more information that I can use, some of which is redundant between newsletters, they serve to keep me well-informed.
