mad

I was just wondering, what do people think is more effective/appealing for audiences, writing from the perspective of the main character or in the 3rd person? I am struggling with this in the direction of my novel and might let the protagonist take over the narrative at a logical point. Also is there a video function with this kind of blog? I find this kind of presentation only (text, not in real time) a little rarefied for this kind of group, like posting on a wall.
