Effectiveness of Brainstorming

Wikipedia on “Brainstorming”.

Although brainstorming has become a popular group technique, researchers have generally failed to find evidence of its effectiveness for enhancing either quantity or quality of ideas generated. Because of such problems as distraction, social loafing, evaluation apprehension, and production blocking, brainstorming groups are little more effective than other types of groups, and they are actually less effective than individuals working independently.[2][3][4] In the Encyclopedia of creativity, Tudor Rickards provides the article on brainstorming, summarizing the controversies. He also indicates the dangers of conflating productivity in group work with quantity of ideas.[5]

iTunes Nomenclature needs a refresh

Or maybe we’re just comfortable with the mix in of apps and music? No, not me. Artist and Album are certainly just wrong. Don’t know how they can make that legacy labeling generic across music/movie/application. Creator instead of artist, perhaps. And just leave album blank for apps and movies. Album doesn’t serve a purpose for apps does it? The link doesn’t appear to work.
