I was thinking about joining NaNoWriMo for the first time and while exploring their site I found this awesome page of links. The one that grabbed my attention was Yarny, a web/cloud-based writing program that is very ADD- and snippet-friendly, right down to the interface.
It's awesomeness covered in awesome sauce with a sprinkling of Ritalin on top. FTW
That looks pretty neat, actually.
