"Diverse views" means editors with a variety of perspectives and general outlooks. "Experienced" means the person in question has been around for a while, is very familiar with policy, and has some experience with related topic areas. With a bit more focus and structure with the involvement of a few experienced hands will make it much easier for uninvolved administrators to decipher what's going on and identify disruptive editors. If I can further clarify or answer any other questions, please let me know.
