"Reading, after a certain age, diverts the mind too much from its creative pursuits. Any man who reads too much and uses his own brain too little falls into lazy habits of thinking." --Albert Einstein
I think the volume is pretty damn low if you limit your intake to dense, high quality sources. The key word here is actionable. How often do you come across something that actually changes your plans or the way you're doing things? It's really very rare, in any field. It certainly doesn't require a daily investment, and probably not even a weekly investment.
A few time I've either been traveling or in crunch mode for a few weeks and been unable to waste time perusing the journals and feeds I usually do. When I finally had a chance to catch up, I found that I could rapidly skim the pile of stuff I would have wasted many hours reading and pick out all the salient information in under an hour.
It's also important to remember we live in the google age and finding information is easy. There's a tendency to suck down information thinking it might be handy later, but a JIT approach to reading and research is probably a lot more efficient. When what to do isn't obvious you can find what's been written fast. Remember that you probably have access through your library to lexis-nexis and other databases that allow you to search pretty much everything that gets published.
People like to procrastinate by reading blogs and "news items" and pretend they're actually doing useful research. In terms of real applicability they'd usually do just as well reading Seventeen Magazine. I'm as guilty as anyone, of course.
