As more of my attention has shifted away from newspapers, television, books, magazines and radio, I've been fascinated by how much time I'm investing online in content consumption…and it's increasing!

I used to read two newspapers every morning (The Minneapolis StarTribune and The Wall Street Journal (WSJ)) and I still leaf through the "Strib", but the WSJ went away a long time ago as I get my business news elsewhere.

My RSS reader has 182 blogs in it along with 17 major tech news sites; 6 video related sites and many others.

People send me links to videos that I'll open at some point…but I always sigh when it's some clearly interesting video that says "59:05" or something and I don't take the hour to view it. I just don't have spare hours laying around.

Twitter gets my moments at stoplights, standing in line, or other times when it's convenient.

A quick back-of-the-envelope of my personal time investment shows that I'm spending between 2-3 hours per day online consuming content. Much of that used to be TV watching or reading books…but the internet is my mind's crack cocaine and I'm so jazzed and stimulated exploring, learning, seeking, considering and playing online that I'm still enjoying it, but am growing ever so slightly concerned that it's too much.

What about you? I'm not talking an addiction or anything, but are you questioning your own time investments? Are you getting the payback on all of that investment that you'd hoped for or expected?
