While I think that Twitter and Facebook can be invaluable for news (including what's going on overseas) and just plain fun, Jon Stewart does have a point about how all of the cable news networks (especially CNN) rely way, way too much on Twitter messages and web site posts and opinions from viewers (local news does it too). Seems like they're trying to fill up space and get viewers "involved" instead of, you know, showing some editorial judgment. Honestly, I really don't care what "funnyballs69" thinks about North Korea. Last night Stewart and The Daily Show talked about this a bit. (Video also here.)
