I've done that to... but you do need to be careful that you're optimising the right thing.
I hate being interrupted - but being interrupted often is often a sign that I'm being the bottleneck in one or more processes. If I force people to queue questions into a single time/place I can end up blocking a whole bunch of peoples work. I might be better off - but the system as a whole slows down... and "urgent" can be a hard thing for people to figure out.
Like the article - I find using interruptions as a sign that there's a process problem that needs fixing to be a excellent strategy.
