We are launching a healthcare anonymous platform using Discourse.
Have taken a cards based UI approach. Check us out at http://careanonymous.com .
As we are developing, would love to hear on feedbacks as well as to learn about people following similar approach. Have done similar changes to mobile theme as well (try opening on Phone)
We have taken a different approach for cards background and text color where we pick category color as background and text_color as text of text. Have overridden default colors
