Just watched a part of a new TV program, "Tough Love" where a guy acts as mentor to about 10 American single women who wish to hook up with someone for a long term relationship but can't seem to find the right guy. WOW it's no wonder with their attitudes and shallow view of life and the world around them that most men would be turned off nor willing to invest time in getting to know them better for anything but a ONE NIGHT STAND. . Speaking about "short lists" if these women represent the average American woman then what sorry social state the American culture has sank, like quicksand, a death trap.
I found years ago that native English speakers do NOT prefer to receive their information by reading but verbally or like you pointed out so yes I think the future of the blog could be these telecast type interviews. The same with the accommodation business I know in the upcoming year or two I need to attach a one minute video link of the interior of each of our 60 rooms and apartments along with the room/ apt rate on my website. It's important to keep updated on such evolving communication and travel related content so we aren't left behind and ignored.
A the internet connections speed increase, this video style may gain more popularity. For most of the non-western world connection speeds are not suitable enough as yet, and the written word holds sway. Those brave bloggers in Egypt, speaking out against the government could not release video blog.
For acomodation, it is the next step forwards. I fully expect the major hostel sites to require hostels to include video footage some time over the next two years.
Unfortunately you are right. I do not click on video interviews. They take too much time -- even with a good connection. I can read so much faster than I can listen. Hopefully automated transcript services that automatically create transcripts from the videos will soon follow but they are not there yet.
