TheFeature is dead now, what a sad thing to hear. It's one of the best mobile industry sources I referred to for the marketing work. There are many interesting and important insights, especially my personal favorites, user experience topics. I've archived quiet many of them but always thought to refer back to the site when necessary. Now its gone forever.
It also reminds me how good things in the cyber world can just disappear forever and how important it is to find a good archive system/mechanism.
