Signed up and it looks great! Looking forward to seeing it grow.
The main reason I actually use Reddit is because there's a community for almost anything. I had a quick browse through the issues/roadmap but; do you have a plan to allow user-created groups or subgroups? For example, ~food is too general for bread-making and so reddit has communities like https://old.reddit.com/r/breadit, which is a great place to ask for baking advice specific to baking bread.
