I have suffered through Gliffy + Confluence for months, so I love seeing new software in this space. This looks very nice, but seems to be missing a lot of important features: boxes to segment networks (a la VPC), directed connections (arrows, filled or not, dashed, etc) and text boxes.<p>I really, really like how good this looks, especially the isometric view. It adds some personality that makes otherwise boring diagrams interesting to look at.<p>Finally, I want to say how awesome it is that you can try out the app without an account and with only one-click. Nothing "sells" your product better than your product, and this website is a textbook example of how this should be executed.
