I thought it was a great comprehensive overview....that's a pretty hefty accusation you make there....no one really has the time to go through BOL indepth..usually that's the first stop for most developers when they run into an issue but not otherwise..if the author has "compiled" an overview using BOL for reference that's ok....it crosses the acceptable boundaries/norms only if it's lifted word for word with no personal input...is that the case here...
