The ease of use. I'm not used to writing in longhand but this was easy. I am able to get my point across quickly and concisely. I have tried other comment systems and they were cumbersome. This one is quick and simple so I don't lose time. I would like it if you could write more than once. Sometimes I want to expand on what I wrote before. I wish there was some way to do that. However, I still think it's very easy and quick. I have been using WordPress for my blog and this is perfect for commenting. I love that you can comment from any device.
