A very interesting thread. Once again, it points to how everyone is looking for something different. No matter what your style, if the content is good, you will have the opportunity to gain an audience.
As for my "style".... I agree with Jeff. It is dry. That's just me. I've tried to spend my energy on making the videos clear, concise, and well organized. Not on making them entertaining (aside from adding a tiny bit of music at the beginning and end just to set the tone...). That's not to say that entertainment value is not a worthy goal. It's just not my forte. I script the videos. Record the and edit the audio. Record and edit the video. Do all my own compression, HTML, CSS, blogging, sales, marketing, etc., etc. Oh, and... I do the photography, too. I'm tired at the end of the day! :-)
My other focus is to always try and keep the end goal in sight. Making better pictures. I feel that too many tutorials are simply geeking out on the knobs and switches. When I worked in Special Projects at Adobe, we called them "Tips and Tricks". Which I'm done with. I'm trying to tell a larger story now. But again, everyone is looking for a different thing. And I think (hope) the photographers who gravitate to my videos will be the ones who don't mind sitting and watching a 20 or 30 minute video, but then after that, are dying to get back out there and exercise their eye... finesse their vision, and make some better pictures.
