While focusing disproportionately on things like programming/ startups and business, both the other articles that crop up here and going through local news/ following links I think I get a pretty broad knowledge on things. I am still able to go really in to depth on the areas I am most interested though.
Probably could be said that I spend more time reading in this way than I should though, its a fine line between staying on top of everything and putting yourself in a place to get things done.
