Google Express Gift Code: how to prevent abuse
Google Express wants to promote itself by allowing member to give $25 to a new user, and get $5 for yourself.
-- So user's friend can start to use express.

But this can be easily abused. - the user can send the gift card to his/her address, and just register another account to use both $25 and $5.

How it should work?
User has to use a different address - express will send express $25 gift card to his/her friend, express will mail this user the $5 gift card. The $5 gift card should be only effective after his/her friend register an express card and add this promotion card(not really use it).

-- Express can reward this user more than $5 - to encourage user to send express invitations to more users.

Same address can be used once.

Original Post from Luke Wroblewski:

G+ Web Preview Update 12/11
Today we're rolling out several updates to our G+ preview on the Web including:

* Visible links to categories on Community pages
* Auto-play of animated GIFs (with a setting to turn on/off)
* Ability to pin posts within Collections
* Clearer indication of notifications on the home stream
* Warning to ensure you don't lose new posts when changing pages

Some of these changes were unanimously requested (people want community categories visible!). Others required us to strike an appropriate balance between opposing feedback (some people love animated GIFs, others don't!). In all cases, we really appreciate your thoughts so please keep them coming using the Send Feedback menu item.
Thanks~
