Some things on youtube annoy me. Vertical video is a biggie. However, as with everything, I consider the source AND I consider what's more important. If a great mechanic who doesn't know aperture from azimuth shows me how to get to the starter bolts off a Honda Element without having to remove have the freakin engine, then I don't give a $h!t how shaky the video is or if I had to scroll forward through 3 minutes of nonsense to get to the meat. The guy just saved me hours of headache and/or hundreds of dollars in repair bills.
If these people *were* trained in video production, I would have a problem with it. Lord knows I see enough crappy local commercials to make me want to vomit. The whole point of youtube was that any average joe could now upload video to the web for anyone in the world to see. I'll take the crappy production that teaches me something over some guy showing off his editing skill in video that have no redeeming value whatsoever.
Two things. Stay away from my channel. :-) If you run across any kids with a lemonade stand in their yard, go easy on them. They're still learning.
