A few minutes ago we updated the mobile alpha with these features:

• The ability for signed in members to add blog posts.
• The ability for signed in members using Android 4 devices to upload photos (we'll be including support for additional devices that have this capability in the next release).
• My Page menu entry for signed in members to visit their own profile page.

Please continue to provide feedback; it's helping us shape the mobile offering, and in addition to working on remaining basic functions (like forums), we have some exciting features coming up. :]
