A fair bit of slippage at the low end due to a rash of technical issues in Second Life during the course of the week, which made searching and much travel impossible.

Data collection note

Due to technical issues with Second Life this week, three samples were unable to be taken. We have substituted the data for the same sampling period from last week to make up for the loss.

Methodology

Mixed reality sites in this headcount are selected for their prominence, either from publicity or real world name recognition. Sites with consistent low traffic (500 or less weekly) may be dropped in future Headcounts in favor of other sites.

We collect data three times per day for each site, one sample at peak concurrency (10am-1pm SLT), one at minimum concurrency and one mid-evening, Second Life Time. For each sample we count the number of people at the site at the time. We average those samples across the week, and then assume that average to hold constant, with each visitor spending a half hour on-site. This methodology does not necessarily include one-time events that generate high traffic missed by our sampling, which we'll make note of whenever possible. Headcounts do not factor in returning visitors, so assume that the total number of unique Residents are likely to be significantly less than the estimated total visits.

We're able to cover multi-sim sites a lot better with this method, so you'll see those higher in the rankings than the previous metrics we were using.
