There's a lot of chatter amongst bloggers in the marketing, public relations and advertising industries about about Venn diagrams and a movement away from silos.

Venn diagrams, for those of you who don't know, are diagrams that show all hypothetically possible logical relations between a finite collection of sets (aggregation of things), per Wikipedia.

The concept was created by a guy by the name of John Venn and they are primarily used to teach elementary set theory, as well as illustrate simple set relationships in probability, logic, statistics, linguistics and computer science.
