What in the world is World Usability Day?
From the WUD site:  World Usability Day was founded to ensure that the services and products important to life are easier to access and simpler to use.  (Even its explanation is simple!) 

Everything from software to your cell phone to your can opener (especially if you have an OXO Good Grips!) has been subjected to the poking and prodding of usability testing.  But, as we've been known to say around the Design team, usability *isn't* just testing.  Each time we toy with a new design or review one that's in progress, we're constantly applying sound principles of design and looking for bumps in the usability road.   

How are we celebrating?
To celebrate World Usability Day, the Design Team is hosting a full day's worth of in-house usability testing to evangelize the testing experience and the importance of being conscious advocates for good design.  We've asked folks from other Blackbaud teams to take The Raiser's Edge 8 for a spin.  If there are snags to be fixed in the design, we'd rather find them here first!

In addition to this, some of us use World Usability Day as another fine opportunity to attend a happy hour.  Or maybe that's just me...
