I'm visiting www.facebook.com on the web browser on a Samsung Galaxy Tab, Android version 2.2, and I can't find any way to log out of Facebook once I'm logged in.
I want to emphasize that I'm not using a native app, but instead viewing Facebook in a mobile browser, in this case the native webkit browser.
Edit: I don't appear to have a "More" button to click on to log out. Any other ideas?
