From a user perspective I can't see how clicking on a tag is much different then only having a categories. I feel you can organize it the way you like may be I use it wrong.
Here on PHPBB I might have clicked on the "NEWPHP topic" and not realize it made a new page till you pinged me on discord.. happen to me a view times on RHDN as well.
Then I did think others might had liked flarum as well but just never tried. I probably still do the survey on some point.. As I starting some topics it made me realize how bad I am off verbally and that might be a turn-away thing for a most people anyway. Currently I have other ideas what could help the activity around hacking games.
