I chanced upon this application while working on my FYP and I think that it’s really neat! The creators made it to work together with microsoft excel and this greatly shortens the learning curve required to pick it up. It is marketed as a tool to analyze social networks such as those on fb but I think it’ll really come in handy in academia. In my opinion, the creators did a great job in solving bugs and implementing new features. I noticed the leaps they made since I was using their software a lot for my visualization.
