How much is too much?

The feed to Dave Astels' blog recently became my 100th BlogLines subscription. (I guess I should have added it a lot earlier, especially after he was nice enough to include XMLUnit in his book on TDD, but the last time I stumbled across the blog it had a ghost-town feel to it and my roving mouse finger moved on elsewhere.)
A hundred blog feeds feels like a lot - but is it really? Is there such a thing as too much reading? Will I get so distracted by other people's opinions that I start to ignore my own gut feel or experience? Or worse still, will I lose the capacity for any creative thinking of my own?! Watch this space, I guess...
