I started with a fluency rating of 14 and have been using duolingo for numerous weeks. It appears that the more I do the lower my fluency rating. How did that happen?
It sounds to me like you work for Duo Lingo and that is why you are in it so often and checking on comments. I do not work for Duo Lingo. I own different software, Rosetta stone, but have fallen in love with this software. I study with it almost every day. This software is far more enjoyable to use. This is the only issue I have found with this software which is quite impressive. I ran a software development team that had a who's who of the top 40 financial clients in the industry. I am impressed with the quality of this software. You say it gets asked 7 times a day, you must be looking at the comments quite often. Are you on the support team? If so, I would say that your replies are not very customer friendly.
