I'm working on a categorization/data mining project using Java JOONE for the neural network. Not as hard as it sounds (most of the time). Must finish this project today or tomorrow so I can get enough money to fuel our startup ( http://www.awesomehighlighter.com ) for the next couple of months.
Just tried out awesomehighligher, I found it really useful - would recomend it to my friends and workmates for sure.
