You know the box on the main page that isn't a chat box, but kind of looks like one? All our personal status updates go there. Awesome for saying "hey, I'm here." But wait, there's more! We can ping people @username in there! And, the most recent and exciting discovery, we can comment to a given status instead of making a new one! Click on the ... in a stays box and we get that option! It's a lot like the formatting of Facebook or Plurk posts. I'm not yet sure when we get notifs about them, but I'll keep an eye out. *Edit* UPDATE! The option to comment is only available on some status updates, not others. Will keep you informed if I suss out the reason.
