I have been espousing the idea that various conferences could choose a tag up front then implore their attendees to use that tag for their blog entries about the conference. This is a simple way to enable information aggregation from a virtual organization.

EDUCAUSE has just announced a tag for their upcoming conference. It looks like the will aggregate the various RSS feeds into a single page.
