I just completed setting up my RSS feeds but only subscribed to 4 or 5. Why? Because at a certain point, it's going to turn into an inefficient time suck. I can't even imagine having 9 external sources of incomng information every day, on top of email and all the links that accrue with that.
This process keeps prompting the question of how much information is too much? Information needs to be processed to have meaning. The human brain can process but so much information within a given time. At a certain point, understanding becomes very superficial: an exercise in skimming. Where's the fun in that?
