• The events-articles-discussions problem was largely rectified with our change. However, one user notified us afterward that she still didn't completely understand the difference between them. We may need to implement some kind of help toolbar to explain. While this isn't the most elegant solution, it will do away with the confusion.
• One user pointed out that we forgot a scrollbar in our main page. Thus, he didn't think he could put on more than a few topics on the main page. This is something we should have made visible.
• The "new post" idea backfired. In particular, one user did not understand that even if she clicked "new post" next to one topic, she could tag it as another topic as well, or change her mind completely and not tag it as the topic she selected originally. We should have probably put only one "new post" button at the bottom right of the screen.
• One user pointed out that there shouldn't be a difference between "home" and "what's hot." In addition, he made us realize that we didn't actually test voting for a topic. This is something we need to make sure to include in the next prototype.
• One user found that there was too much information on the screen, particularly since she couldn't tell articles apart from options. We believe this will be rectified with the use of color, howehowever.
• One user made the good point that he should be able to reorder topics in the main window. While we're not sure if we'll do that, we'll have to organize the topics in the "select viewable topics" window.

Conclusions

We've decided to stick to our initial design. While there were a few problems, we believe that they can be rectified with better information scent and visibility. We appreciate the simplicity of the design, and the fact that it could be easily displayed on a mobile screen. We will need to fix some of the design issues we encountered. Most notably, we need to make the interface somewhat more learn-able and make the items on the screen more visible. We believe that most of these problems can be fixed in the actual implementation by the use of color and widgets.
