 - Yes, filtering by category is a good idea


I like the idea of filters, but I want to be able to look in each one easily. If I can daily click on
- general
- contest
- sports
- crypto
- languages (set up as they are needed)

And get a list of just those. But I want to start on a page like we have new - not permanently stop a category from showing.

Each language would be a category. not a separate place for that. So a crypto contest in German would be in three categories set up by the author.

Great idea :)
