Starting late last month, the published statistic that showed an unprecedented ongoing reduction in Second Life land area was disabled (perhaps permanently, the Lab hints). The raw data is still available, however, and the decline continues.
We've had no luck in obtaining response or comment from Linden Lab about any of this, but Wagner James Au at New World Notes has fared rather better. However the statements from the lab are fairly tangled and unclear.
The Lab claims that the figures misreport, which is technically true. All of the statistical systems give incorrect information at least several times each month, but according to Jack Linden, the numbers are actually sort of correct, and indeed even skewed slightly in the Lab's favor (the reported losses have been far smaller than expected) -- but just misunderstood.
