I despise them. I'm convinced that they became "cool" purely for two reasons:

1.) Bosses loved the feeling of superiority they had by having their own office but everyone else is sitting out in the open where they can easily see them all and bother them at a moment's notice.

2.) Fresh out of college grads would see them and get this feeling of a cool, buzzing, hypersocial hive that made them feel all good inside.
