Restructuring the Linaro website(s)

Linaro now has around 40 sub-domains, all of which are perceived as individual sites by search engines. Only 5 of these are linked to from the linaro.org home page and many will not be getting significant levels of traffic. We need to bring these together into a logical structure to not only help accessibility, but also to boost our ranking in search results. We want to discuss this structure and if there is a reason to keep any of our online services as sub-domains.
