This story is actually from a few days ago, but we didn't quite get to it. It's still pretty cool news, even a few days later, so just in case you haven't heard it...
It looks like the FCC is finally doing something about telemarketers that can have a serious impact. They plan to publish the phone numbers of telemarketers on a weekly basis. Their concept is that by publishing the numbers, developers can create automated apps which can more effectively bock annoying spam calls before we even get them.
Obviously, this primarily would work for folks with cell phones, but the FCC also indicated they are working on a solution for landline phones. Finally, we can start to cut down and possibly eliminate robocalling!
