Online chat with Mike

As you're probably aware I am a large heavy an extensive Google user (Gmail, Google Apps and the like) and therefore tend to be sitting in one of their products whenever I am online. This means that Google Chat knows I'm here to be chatted with.

And so I've added "Chat with Mike" to the right-hand menu.
It'll have a green indicator to say when I'm actually here and just click to start chatting.
