[Sugar-devel] [ANNOUNCE] Groupthink 0.1 pre-alpha

[Sebastian Silva]

I love the API, great contribution Ben!

I also love the name, Groupthink, from WikiPedia:
"Groupthink is a type of thought exhibited by group members who try to
minimize conflict and reach consensus without critically testing,
analyzing, and evaluating ideas. Individual creativity, uniqueness,
and independent thinking are lost in the pursuit of group
cohesiveness, as are the advantages of reasonable balance in choice
and thought that might normally be obtained by making decisions as a
group.[1] During groupthink, members of the group avoid promoting
viewpoints outside the comfort zone of consensus thinking. A variety
of motives for this may exist such as a desire to avoid being seen as
foolish, or a desire to avoid embarrassing or angering other members
of the group. Groupthink may cause groups to make hasty, irrational
decisions, where individual doubts are set aside, for fear of
upsetting the groups balance. The term is frequently used
pejoratively, with hindsight."
