Ours is a fast moving industry and as times goes on I find the need to specialise more and more. However, I believe there is a great value in at least having a passing knowledge of as much of our field as possible, IT pros can learn from developers and .NET team from Java and of course the other way around. 

I find the best way to try to keep abreast of new ideas is to listen to podcasts; I personally find it hard read enough blogs, but I can find time to listen to a podcast whist travelling or working around the house. Here is a list of a few I find give me at least a feel for what is going on, I still feel that they are a bit Microsoft focused, so interested to hear any other suggestions
