A few thoughts for you…
- Love the custom loading animation!
- The category icons are a nice touch.
- Pulling in user avatars from the game is very cool.
- Font size is a bit small for me, I’d be increasing it a notch in the browser.
- You do have a lot of tags, but that’s probably better than a lot of categories.
- The tag name format “group:tag” is unusual, and arguably not 100% necessary – but if it’s working for you and your users, that’s the important thing.
- The Closed Issues category is an interesting approach – I think I like it.
If most users are coming to post something, landing on Categories rather than Latest could be more straightforward – though your header links do provide good starting points.
Also, noting your Blokreations category of image posts, there are a bunch of add-ons you could look at to highlight images in that category, select some for the homepage, even collect them in user profiles:
