Back in a learning mode once more (currently wrangling information on XmlTextReader and multithreading).
Also been rediscovering the wonderful DotNetRocks shows, check them out - great for long journeys / passing time in airports!
My current information source of choice (besides the internet) is the book Programming .NET components by Juval Lowy , best book I've ever read covering the more advanced .NET topics, such as threading, security and app design...very nice and a definite 'must have'
