I would say it helps BI developers build systems that react fast. For instance you can monitor blogs and news feeds, sending automatic alerts to key persons so they can act directly in case of bad publicity.
You can also use StreamInsight to do the collection job and initial filtering when you have environments that produce high speed data output.
