Hi! This is my first post.
I have absolutely no clue what's the difference between the Misc and the Uncategorized categories. Perhaps they are redundant?
Perhaps you can give a more compelling name to the category or the categories. For example over there at the Signal Community they have a lively General Discussion category to discuss wider issues. I haven’t found an equivalent here. Over there at the Fairphone Community they have a category called The Industry (again, to discuss wider topics) to give you two examples overall. Something similar would be interesting here. Your Misc and Uncategorized categories are rather dead in comparison.
