What are the Pro's & Con's of having a YOUTUBE Channel? I need to know!?

No, its not immature. Im 17 myself, and I actually like what your doing and ill subscribe. Me, I do call of duty videos and stuff like that.. :P Pros would be subscribes, and thats about it.(because its youtube.) Theres only one con that I can think of, which would be the more subscribers you get, the more videos you will be expecting to be putting out. so dont take breaks! hope this helps
