Through December 5 of this year, the number 10 most-read post on this blog was What the bridge collapse videos tell us about YouTube's audience.
In this post, I noted that although YouTube is a destination for posts abut news with strong visuals, the interest among YouTube users in seeing news about the tragic collapse of the I-35 bridge in Minneapolis this summer doesn't match the interest indicated in page view counts for more fluff stuff.
I haven't changed my opinion since.
