VERY INTERESTING INDEED according to this it looks like Momo might start posting again under Google + (??) but I'd guess this will be a closed group, like you can have on facebook. You can apply to join, but only the holder of the account can accept you as a member. Another thing, I believe when you sign up for that type of account, you have to give your email address. If you have a wordpress blog and someone leaves a comment - it records the IP address of the person leaving the comment, whether they want you to or not!
