Some interesting news in the ongoing study of site statistics.
Fact: 42% of spankers have been active in the last 30 days. This number was about 91% in August. Did something go wrong? I don't think so. I think it's part of the business of building out the network. Your friends are what pull you to the site, and most people on the site still have only 0 or 1 or 2 friends. As the network builds, the average frequency of visit should build.
Fact: the average (mean) duration of a session on the site is 3.7 hours.
Wow! I have to go now so I'll be brief on this one. As you'd expect, the number is skewed by a very small percentage of very long visits. Also, it includes visits that may involve plenty of open browser windows.
On the other hand, this figure is calculated as the time between the first page load and the last page load of a session. So, if you visit your Inbox, spend 15-20 minutes viewing links, and then jet without any other page load, that was counted in the 3.7 figure as a 0 minute visit, not a 15 minute visit. In other words, there is some slop on both sides, but the figure is real.
Linkspank is sticky! Yay. That's a good Christmas present.
