Each month we use the Alexa statistics to calculate a interest points in a series of long running customization sites.
The sites used for the index include:
WinCustomize, deviantART, Deskmod, Neowin, Skinz.org, SKinbase, Customize, Pixtudio, Skinnables.org, Teknidermy, ArtUproar.
Taking their Alexa ranking we use this formula: 1E6 X (1/Ranking^1.25).
In January, the total score was 9.0. This month it increased to 9.5 with much of the increase due to increased popularity of WinCustomize, deviantART, and in particular Neowin who saw its ranking jump nearly 10% in the past month.
March should be very interesting since that will be the unveiling of an immense amount of new customization software and streaming video on how to make skins, themes, and more.
