This is something we still need to improve. Too few visitors to reddit understand or even know about how this vast network of user-created reddits should work. See, here I go wanting to mock a new redesign up in photoshop...
I've been a reddit lurker for 4 years, and I was one of the hordes clamoring for tags back in the day. When subreddits were introduced instead, I was a bit disappointed. But now, these many years later, I can see how the subreddits become independent communities in a way that tags would never have accomplished.
I'm still proud of you guys for that decision. Thanks for a great site that I still spend way too much time reading every day.
The main problem is, reddit isn't helping its users discover those needles in the haystack. It's down to serndipity or sheer bloodymindedness clicking next next next while looking through the list of subreddits.
Maybe leaving users to create other sites mapping out reddit is a good idea, but reddit could do a lot more to aid discovery.
