We all know the sedentary lifestyle of your classic IT person can lead to ... shall we say ... bloat. I regularly joke that the only thing bigger than your typical (Unix) system administrator is his beard. I jest.

Anyway, we do what we can to avoid the bloat, including running (literally) some form of carbon-based defrag on a regular basis, to compact that extra space.

... and it may be working across the industry.

Here's my evidence.

When registering for a Microsoft developer event in 2005, notice the shirt sizes go to 6XL ...

But, for this year's Tech-Ed Developer conference, only 4XL ...

I'm going to assume that Microsoft has leveraged the cool data-mining features in SQL Server to determine that 5XL and 6XL sizes are vanishing.
