Meaningless to two decimal places
The Compete Attention 200™ is a ranking of 200 sites based on time spent. UPS, for example, ranks way higher than Fedex, and MySpace is number one.
This is just silly.
Any website that attempts to improve time spent on every page (or pageviews for that matter) is just wasting time. What matters is intent. Permission. Action. Retention. Likelihood that ideas get spread. Clickthroughs.
Just because we can measure it doesn't mean it's important. Anyone want to buy stock in the globe.com?
