FAQ: What are the blue shaded areas in the Galaxy?

The shaded areas on the Galaxy are "ThemeClouds" which are analogous to ThemeView™ Peaks. ThemeClouds provide a two-dimensional representation of theme strength. Areas with higher thematic content and/or document density are more intensely colored in blue. Areas with less document density and thematic content are more lightly colored.
