I was going to use this feature earlier today but I was put off by the fact that it displays the full name of the person, which made my small, casual comment seem weirdly formal.<p>I also don't like the box around the name. It adds a slimy Facebook/Twitter feel to comments, drawing too much attention to the frenzied "tag me!" social graph hype. I like the idea of being notified when someone mentions you in a comment; I just wish it was more subtle, and less distracting to the conversation.
