Seriously guys, I couldn't make this up if I wanted to. Android announced Galaxy Nexus contest on Google Plus and directed followers to go to Twitter to see contest rules. And of course, the whole contest is being run on Twitter.

Almost every response calls them out for using Twitter instead of G+.

The Google Web Quality team actually recommends you like your own stuff. Of course you can always separate what you do and do not want to know about so that you direct Google in the direction you want.

Greetings all members – I'm a fresh poster on your messageboard and I believe I would do best to give a few details about myself. Umm, I'm 21 years old, male, and I enjoy reading german at my school. I certainly can't wait speaking with all you guys... Farewell for now

The Google+ TOS does not allow contests.
