One of my favorite sites the last few months is Technorati.
Here’s part of the reason why:
For example, the blogosphere often “lights up” with respect to a particular topic (e.g., the President’s National Guard scandal, rollout of the iPod mini at MacWorld Expo, etc.) in response to a recent article or news report.
That is, many bloggers start “conversing” about the topic in response to the breaking of the news in the mainstream media.
Not only does the present invention enable tracking of these conversations, it also enables the identification of individuals who were talking about the topic before release of the news.
As will be understood, the ability to identify such “conversation starters” or influencers relating to particular topics is extremely valuable from a number of perspectives.
