Hey everyone,

I just read a PDF located at the following address:

http://www.nielsen-netratings.com/pr/pr_070710.pdf

From what I gather, it seems that due to the increasing pervasiveness
of applications based in AJAX and other media driven applications
contained within a single page, Nielsen has taken to using the primary
metric of Time on Site.

Does anyone have any opinions on this or can anyone tell me how this
affects them? For us, not having any relationship with NetRatings,
and very limited involvement with what people would consider Web 2.0,
I have no perspective on the magnitude of this announcement. Judah
always preaches 'Context' and I agree with him on that. So, having
said that, is this transition slightly premature in that it only
applies as a major measurement of top sites in addition to their
traffic for engagement, or is it something so big that I just can't
conceive of it yet?

I realize there is virtue and value to measuring the attention span of
the user. I see it as a margin to shoot for in terms of presenting
useful options on the site. In the event that we would add numerous
videos or instructional content, I would expect its useful in knowing
how long people like their videos to keep feeding them things which
conform to their expectations. Beyond that, and as for using as a key
metric on which to base performances, I still see it as subordinate.

Maybe Jim, Eric or Avinash have some insight on this or can lend some
wisdom here?

Sincerely,

Daniel W. Shields
