According to the goofballs at Liberty Post, Alexes shows them to be out-doing FR?

There are several ways to measure a web sites traffic.
Page views is one that people have used that is notoriously meaningless.
For example, FR used to limit the number of posts viewable on any particular thread to 20. Now it is a selectable preference, and a viewer can have as many as 100 posts viewable on a given thread. That means that the 'page views' for a given thread are potentially one-fifth of what they used to be ... essentially a meaningless statistic that give no indication as to numbers of viewers.
Hits is another meaningless statistic. I could build a web page with a million little tiny graphics on it, and one person could view that page and I would get a million "hits". Meaningless.
The 'Reach' category on the other hand, shows the number of individual computers accessing a site, and is the best indication available as to total viewership.
