1. Stop the music...period. If you're too embarrassed or afraid to speak, use subtitles. I don't share your taste in music, but I'm interested in the content of your post. Don't be angry that I clicked off your thirty-five minute video after the first fifteen seconds because all I hear is music. You get what you deserve. Youtube is not MTV and it shouldn't be used that way. Plus you might be in trouble with DMCA.
2. Stop using "we" when presenting tutorials or informational material. "We" aren't doing anything; you are presenting. Keep things in context. How do you know what I'm doing? Probably not the same thing as what you're doing for whatever reason.
3. Stop using automated, robotic voice-overs. The fakery is apparent. No-one wants to listen to Siri narrate your entire video. Again, if you are too embarrassed to speak, just use subtitles. Still annoying, but to a lesser degree.
4. A six-second video is not content, it's sophomoric garbage. If you choose to upload content, make sure there's some value in it other than lampooning some stupid thing like Lewis picking his nose in class.
5. Get a damned tripod AND USE IT! They're relatively inexpensive. Some of these videos I've watched border on having to take Dramamine after about five seconds to avoid barfing on my $1,200 laptop and having to pay someone the same price to fix it.
6. Speak clearly if you choose to do so. No-one can understand you if you sound like you've got a mouthful of marbles. Again, use subtitles if that's a problem.
While my comments might be interpreted as somewhat vicious (read "bitchy"), I feel these are some of the things that need to be said but not, out of personal respect, directly on those channels observed.
