I just posted my own Skritter story on the Skritter blog:
http://blog.skritter.com/2014/05/how-skritter-helped-me-stop-worrying.html
The article also contains details about an experiment I conducted to check if Skritter could help me maintain my character writing ability (I needed to pass an in-class exam with tons of handwriting), as well as some thoughts on using Skritter in general.
I'd be very interested in hearing your thoughts, as well as your own stories!
