Thanks to Scott Hanselmann, I've just been introduced to some serious brain-damage. :) Things like Glimpse do not pop-out every day and so it was really weird to see a framework that - in your browser - displays debugging information from the server, executing the MVC web application on .NET stack.
This is really groundbreaking, but at the same time quite needed, technology that lets you know what is going on with your application. Kinda like debugging on production servers. :) Head there to find out more.
"What Firebug is for the client, Glimpse does for the server... in other words, a client side Glimpse into whats going on in your server."
