Intelliseek, the online PR and word of mouth monitoring service, said it upgraded its BlogPulse service to version 2.0, growing to take account of 9.3 blogs and keeping archives for six months (rather than two). The new version of the service allows for the custom creation of concept categories that can be graphed across the blogosphere over time, according to MediaPost. It also now reads more than a sites homepage, digging down into article content.
