Unlike other rating services, Agilience is totally independent. Agilience rates sources based on public information available on the open internet. The rating process is entirely computer-based and we are rather stringent on keeping its independence and objectivity.
We use today the social graph of Twitter as it is one of the largest open social graph available. Besides, Twitter is often used as a notification agent of web sites and blogs and therefore provides a good starting point to discover interesting sources. We use Agilience 3S technology to explore the graph semantically and socially.
