In the Wikipedia app for Android, no information is provided about the license or authorship of the content. This is a violation of CC-BY-SA and sets a very bad precedent for other users of Wikipedia content.
License and Authorship info should be available in the options menu, preferably at the first (initial) level, and/or via a long-tab into the content (the latter could at some point show the author of the respective word - but that opens a whole new can of worms). The "About" page with info about the App would *not* be the right place, as it's counterintuitive and hard to find (we wouldn't accept that for other apps, would we?)
