Rest assured, there's someone whose Skritter strokes are even uglier than yours:

Three major issues that influence the way I write:
(1) I got used to different ways of simplifying strokes that still comply with the script recognition.
(2) Sometimes exaggerating a strokes is needed for immediate recognition, so I tend to exaggerate certain types of strokes.
(3) My method of using a touchpad on a laptop is probably quite unique.
What do your strokes look like? Has Skritter helped to established a new Chinese handwriting font style?
