An informative comparison on Grammarly and WhiteSmoke.

I personally use grammar checking software when I don't feel like editing my own work or another persons'. I found this pretty informative read on the difference between Grammarly and WhiteSmoke. I know its not very good to use a grammar checker but if you know someone who needs help then it may be good for them.
