Data Explained
Page Requests The total number of requests for web pages (aspx files in particular). Note: RSS requests are not included in this number.
Sessions The number of unique sessions. A session is created when a browser firsts connects to a site. A single session can contain any number of requests.
RSS Requests The total number of requests for all RSS feeds. RSS is an XML-based feed for syndicating site content. Note: this is not the total number of subscribers, only the total number of times the RSS feed was pinged.
Activity Activity is an aggregate of the total number of blog posts plus the total number of trackbacks and comments. This number is multiplied by 200 so it scales with the other numbers on the graph. This is used for trend analysis; in particular, inferring if blog activity influences traffic.

How the Data is Collected
The data is collected via a .NET HTTP Module; the cool part is the scrubbing: first, no hits to images or other files are included, and do not factor into the number of sessions.

Second, all user agents are scrubbed and bots are removed from the data collection. This ensures a substantially less inflated view of sessions and requests, often accounting for a huge number of false sessions and page requests.

Third, all of my IPs and related data is scrubbed; since I'm my biggest visitor, it's important that I don't contribute to my own stats.

Finally, all bogus referrer, comment spammers, and other "noise" is scrubbed. The result is an extremely clean dataset.
