I taught a few sessions of a "keeping current" workshop that I put together for work a while ago which was mostly/usually about what RSS is and how you can use it in your current awareness strategy instead of subscribing to and NOT reading dozens of print journals. But while I was teaching these sessions, a recurring theme arose.
Finding information's not the problem. We all know that "If I only knew/read/skimmed everything in this book/journal/website/etc that would really help my job/research/homework/relationship/parenting/etc." There is enough information out there -- factual or not, professional or not, valuable or not -- to satisfy every individual need for knowing more about whatever they want to know about. The key is in choosing what "stream" to follow, or float down rather. You have to be pretty selective about what you're going to be tracking regularly. There's a lot of content out there but there's also a lot of overlap. What one Corvette expert has to say on a regular basis will repeat much of what another has to say. You can't listen to them all.
Well, actually, you can almost. If you narrow down your focus enough, you can still keep pretty good tabs on all the "experts" in a field. But then you can't do anything else. You can be yet another expert on the topic of marsh hens but when someone asks you about guineafowl you'll be stumped. Of course, if you don't focus at all, you'll be reading about a million and one topics and not get enough depth to be of value in any of them.
The best path is right down the middle. Make a list of your primary interests and primary specialties and focus on them. Read some books, read some blogs, search for some current articles on each of your main topics and do so with some regularity.
And remember to shut it off once in a while. Dive into something completely new once in a while. Or turn it all off and have a break. You'll be amazed at what bubbles to the surface when the turbines are turned off or pointed in another direction.
So what do you folks do to "keep up"?
