The whole UI concept is nuts. Share is probably the most used function. Now lets see what happens on an Android tablet if you want to share a photo one of your friends has shared.
1. Facebook App: NO "share" button at all. So you must click
on a photo to open it in full size first, then select "share" from the
Android options menu but this stupid app starts sharing this as your own
photo - it even asks where the photo was taken!
2. In the Browser:
Firefox for Android: Facebook site as intelligent as it is, opens some
crippled mobile version of the site that looks like Netscape 1.0 and
again NO "share" link - here there is NO way to share something.
Opera for Android: Here for some unknown reason I finally see the normal
facebook website including a "share" link. Unfortunately the facebook
site uses some stupid scripts that will screw up the Opera browser at
Bottom line: There is no user friendly / working way to use facebook on Android!
