Dailylit.com is great for getting extra reading in. Beyond that I have "Hard" book that I make sure I read at least 30 minutes a day, to ensure I'm not only reading fluff.

As far as articles go, when I find something that I don't have time for right then I drop it into a "Consume" folder in my bookmarks, and then periodically I go in there and power through some of the stuff, it's not optimal, but as long as you have some way of making sure you periodically check it, it is a trusted system.
