I get the desire for differentiation, it's important otherwise why would someone choose your product over another. I think it's key though to better understand the words that your competitors are using to describe the problem/space coupled with the words that consumers are using to describe the problem/space. Understanding this word-scape will help you to better craft your on-page copy along with identifying the words that best describe your unique value proposition.

I'd also consider studying/contacting the twitter followers of your competitors. That would be a direct method of identifying solid potential leads.

Who are your competitors? Can you give me links to at least 3 of them?
