I browsed around it for a good 20 minutes or so. My initial knee-jerk reaction is that I would not want to join a community with no ability to create or join specific areas that could be narrowed down to more specific topics. “Gaming” for example (and as someone else already mentioned), has to be video games, of all forms (retro, console, computer, homebrew, hacks - from all years) alongside board games, card games, browser games, children’s games, educational games, physical toys, etc. It’s a mess, to me at least. There aren’t even that many categories.
It is also very sterile-feeling. I appreciate a good old-fashioned text wall, but no options for background and text colors even? (Maybe that is an option if you are able to log into the site)
