There is no such thing as "regular folk". People with an interest in photography will follow photography blogs, people with an interest in music will follow music websites, etc...

e.g. music making forums such as GearSlutz / KVR have 380k / 390k members. DPReview, for all things photography has millions of posts. And only a small portion of people are active, the immense majority just reads without registering an account - for instance the current ratio in gearslutz is 8:1 (714 members and 5929 guests).
