I really like those context-switches during my workday, never thought that would be a problem for other people. Thanks for the interesting post.
Currently I manage a bunch of eLearning and eAssessment services, like a Moodle installation for 25k users, at one of the biggest universities in Switzerland. It's a very heterogenous environment with a shitload of different systems, different tasks and different objectives from all directions.
Context switches keep me awake and my day interesting.
