I'm working on building a local music and art blog at wichitacreative.net. Basically, I have 2 main parent categories: "Artist" and "Band". Each new band/artists that gets added to the site gets their own subcategory (Band > Band #1, Band #2, Band #3, etc.). Since we are adding new artist/bands to the blog so frequently, I'm worried that eventually the number of subcategories we have on the blog is going to get out of hand. Should I be using tags to organize the bands/artists by name instead? I've also played around with the idea of using a custom taxonomy like "Artist Name" and "Band Name". Will any of these methods work better than the other, or am I just worrying about nothing?
