Here are some interesting stats:
Unique vistior represents the # of actual differnet people. Some times talk about # of hits or visits and such. But 1 person can visit many times.
For instance, on August 20th 877 people visited this site more than 50 times!
There were 76,472 unique visitors in a given day (the # of monthly uniques is far less than the daily uniques X days in month since many of these people will visit again tomorrow and at other times).
In fact, as a depressing stat, 70% of peple who visit this site only visit ONE time and then never visit again. In 2003, only 1.4% of the year's visitors are "regulars" (visit the site many times per month). But 1.4% of the year's unique visitors is still 201,000 people.
In fact, in 2003, there have been roughly 14 MILLION unique visitors. Though like I said, only 30% of those people ever bothre to return. Though, this stat has to be taken with some grains of salt since it is uses cookies and IP info and such (web log stuff) to determine this info.
There's about 400,000 users who visit the site fairly frequently (we have about 700,000 actual member accounts here to put things in perspective).
