Sequence diagrams are about the only UML diagram I feel guilty about not drawing - I know they can be useful in some circumstances but generally drawing them with most tools I've used is about as pleasant as root canal treatment.
However, this looks nice and simple (editing text!) and I particularly like the hand-drawn style output.
I love the interactive nature. There was a Sequence Diagram I wanted to draw but too lazy to draw it. As I stumbled on this page, I just drew a complex Sequence Diagram in minutes. And it was fun!
