Re-posting the "Google Plus" Rules
I originally put this on Plus, but I wanted to keep it handy for reference:
#1 - The first rule of Google Plus is, you do not talk about Google Plus.
#2 - The second rule of Google Plus is, you DO NOT talk about Google Plus.
#3 - If more than two people in your stream have already re-shared a post to what appears to be similar Circles, you don't need to.
#4 - Choose your Circles membership wisely.
#5 - One post at a time.
#6 - No animated gifs.
#7 - Hangouts will go on as long as they have to.
#8 - If this is your first time in Google Plus, you have to post.
