Have you heard about Sparktoro? Rand Fishkin's new business venture? If not, you should check it out.

Here's what their site describes them as:

SparkToro™ is in the early stages of building data and a software product to help marketers, public relations professionals, and entrepreneurial teams learn more about the audiences they want to reach.

My personal experience:

I've used their SparkScore tool and their Fake Followers Audit. And find both of those tools to be amazing ideas. On the strength of those two ideas alone I'm pulling for this company's success and hope they realize their full vision. One of the major problems with social media, especially Twitter, is the noise that bots and trolls create. Cutting through the BS and finding the real value of what you see on Twitter? I can't even begin to calculate how useful that is!
