Once upon a time there was just a little bit of information available on SharePoint, and you were happy with all the information you could find. It was the time that Reflector was your best and often only friend to get the details on how thinks were working. Those days are over. It is now completely information overload... although a lot of interesting features of SharePoint are still there to be uncovered because no one knows about them. Documentation is missing, and Reflector is your best friend again. You also see more and more sites that dedicate themselves to just a small part of the SharePoint platform, like sharepointsecurity.com, dedicated to... ah, you can guess.
