Everyone loves Google. They want to be everything to everyone, and they’re getting pretty damn good at it. Once you start using their services it gets easier and easier to migrate more of your life to them. But there’s a slight problem.
Google, like any other legitimate service provider, encrypts login traffic, but not your content. So the moment you’re signed in they switch to plain-text communications and send everything to you in the open.
This means your mail, the news sources you read, your calendar events – are all able to be read by someone with access to your network traffic. This could be your employer at work, people monitoring the wireless network you’re using, etc. This isn’t good.
