Jessica Moss
Jessica advocates answering forum questions as a means of self-improvement, emphasizing how looking at the problems of different people inspires thinking about things in a different way.
Ms. Moss also gives back in a variety of ways: volunteering at United Way, Meals on Wheels, painting school walls (not graffiti!), and her University of Virginia alumni group.
As one who knows something about Business Intelligence and SQL Server, and having heard Jessica speak on the topic I can heartily recommend her books:
