If you are obsessed with what your competitors are doing, then check out Competitio.us - an excellent resource for making the process of competitive research much easier.

The service enables anyone a simple way to track who competitors are, what they are doing and most importantly how their activities affect your company and your bottom line. "Competitors" can either be a company, a service, even a product. Competitio.us also enables users to find, save and share news about the competition you've identified through a rather elegant "clipping" system. There are quite a few other noteworthy features including the ability to create a comparison matrix, RSS news feed subscriptions, and traffic data comparisons from Alexa. Users can track multiple projects and collaborate with members of your team.

I first came across Competitio.us about one year ago. While it fell of my radar after initial testing, one of our readers sent in a request for free, easy, ongoing competitive research tool. Competitio.us is a good one - so enjoy - setting up an account would be a great weekend project.
