One of the areas I work in relates to Business Intelligence and Data Warehousing. It is fascinating to learn how to effectively present large amounts of data to make it useful to the people that need it. I am constantly surprised and amazed at what information that can be pulled out of data if you dig deep enough.
Working as a SharePoint admin always keeps me on my toes. The most exciting things I love to see happening is how this is changing the way people work together. With more people going mobile, keeping everyone on the same page will always be a challenge.
