Tracked

Tracked.com gathers, organizes and analyzes information, communications and connections about companies, industries and businesses.

Tracked.com is what you get if you were to mash together Yahoo and Google Finance, with aspects of Twitter, Facebook, and LinkedIn. The service looks like Yahoo and Google Finance, but functions like LinkedIn, as its atomic elements are people and companies, not tickers. Thus, there are pages for literally any business entity. Every item in the service (stock quote, chart, news story, 13d filing, person, company) can be shared with other users of the service.
