One source of information you should absolutely make a part of your regular reading is the blog “SQL Server According to Bob”. It’s written by not one, but two guys named Bob—Bob Dorr and Bob Ward.
These individuals are perhaps the most widely respected deep technology experts on the SQL Server team. They’re the most senior members of the SQL Server support organization. Rest assured, if you have a support call about SQL Server referred to one of the Bobs, there is no higher authority.
