I guess the bad news just keeps coming for Yahoo. On the same day their long-awaited Panama ad software fully launches, the wires are reporting that News Corp. sites have overtaken Yahoo for pageviews. Maybe so. But it's a News Copr press release they are citing too. Looked at closer, Yahoo counters that with their use of Ajax/web2.0, users don't go through as many pages, and Yahoo claims that users actually stay longer on their sites. So, the battle to define good metrics on site usage continues. But generally, it seems like "page views" will likely go the way of "hits"...close to meaningless.
