I am a huge fan of interactive tools as a way to generate a World Wide Rave (when people are talking about you and your company). The best interactive tools tend to be free, are easy to use, and provide meaningful data. And when they do all those things, people talk about them and share them.

For example, HubSpot has two great tools, Website Grader and Press Release Grader. The simple and free tools have been used to grade hundreds of thousands of sites and press releases. And tons of bloggers have talked about the tools, generating thousands of inbound links.

Last week, Douglas Karr released on his Marketing Technology Blog a Tuned In Calculator. The idea is deceptively simple. It takes your RSS feed and analyzes it for how often you use egocentric words like "we" and "our" compared to how often you talk about your readers, your buyers and their problems. As Douglas says, "If you're always talking about yourself, you may not be Tuned In!"

Here is a link to the Tuned In Calculator.

When I first tested this blog, I got a 9 (awesome). But a few days later when I tested, I scored an 8 (caring). I'll need to figure out why the difference! Maybe Douglas tweaked his algorithm yesterday.

Thanks Douglas, for taking an idea in our book Tuned In and creating such a great tool.
