UPDATE:

Of course Steven is correct. But that’s only true if you look at the world the old way. Of limited attention.

I look at it as a sea of Google keywords, though. So, let’s go looking.

Are there any “plumbing vlog”‘s? No.
“teaching vlog”? Yes, 27.
“law vlog”? Yes, 4.
“scrapbooking vlog”? No.
“cooking vlog?” Yes, 119.
“skiing vlog?” Yes, 2.
“learn German vlog?” No.
“movie star vlog?” No.
“tech geek vlog?” No.
“cool vlog?” Yes. 390.
“soccer vlog?” Yes. 1.

Should I keep going? When all of these categories are as competitive as “tech journalist” (91,300 results) then I think we need to worry about production values.

Not every video blog needs a huge audience. Have we learned nothing from the Long Tail?
