It might have taken them nearly a decade to do so, but the most popular knowledge hub on the net, Wikipedia, has finally launched their official mobile optimized site.
The newly launched mobile adaptation is supposed to be optimized for all “fully-featured” smartphones, including the Palm Pre, iPhone, Kindle and Android platforms. So far both English and German are supported, but there are more to come. I’ve heard that visiting Wikipedia on the Palm Pre automatically redirects you to the mobile site. Doing so on the iPhone does not, at least yet.
