I've gone off news. The media loves pessimism, and I am pretty much a pure optimist, so I don't do newspapers (other than the 6 sudokus in the Daily Mail if I need to fly to London), don't watch TV and pretty much the only info I need I get via my RSS aggregator - you can see what I find interesting here - it is pretty much all techy info and security, plus some Dilbert, xkcd etc.

Over the last 3 years I haven't found doing without the news has impacted me much, if at all. YMMV.
