At the moment, I just sort of browse HN/Reddit and look at books being published.
How do you stay informed?
Really a good majority of the stuff that is released at any given moment is pretty worthless.
Fixing something that doesn't need to be fixed, begging you to move to something for the sole reason that its new without a valid reason, etc etc etc.
You don't have to keep up at any given moment. Things that are actually worth paying attention to will filter through eventually.
Unless you are unable to do something and need a new technology to solve a problem, but then, probably be best to stick with things that have a track record of just working.
If it looks cool do some side R&D with it, but until you see expected results I'd take any new technology with a grain of salt - especially if it's proprietary.
