I have a question on terminology. I just came upon this thread and I admit I don't understand the class concept, but after reading the first post I have a question. Why is the one on the left considered a feather stick? I thought a feather stick needed the stick attached. Don't the feathers help ignite the stick they are attached to? I obviously don't know what a feather stick is, but my limited knowledge is based on what I see others calling a feather stick. If I had four or five of those (on the left) I'd call it a bird's nest, so my understanding of bird's nest must be off, too. Or is a bird's nest finer material like grasses? Maybe there is some overlap, or it's subjective? Can someone help out a newb? And explain what the "class" is all about?
