Thank you, regardless of my interests in promoting the idea of using such a tool, we made it because we have found time and time again that always upto date visual documentation such as UML is invaluable, especially as projects get older and bigger.

Otherwise, in general we're far more interested in constructive criticism (or even just normal criticism) of our philosophy (and tool) from a place like HN, rather than trying to score a little free "advertising". When the time is right, we'll do proper promotion, and it won't be by spamming forums.
