intros are pointless and stupid and usually detract from a video. you click through to something to see what is advertised in the thumbnail and the title, so it's a bit outrageous that the thing opens with some ego-centric "mY cHaNel!11" introductory bit. The channel, or you personally should come AFTER the video/entertainment. take a look at most sketch/comedy shows. they don't do self-referential humour until their show has gotten to the point where typical audiences are well acquainted with the cast.
and if you aren't making these to try and be entertaining, then why are you making them at all? or why are you posting them on a public forum?
