"... nobody can ever be forced into having a party ... the forcing is what makes a party impossible. If a host made you promise to go to his party before you could pass comment on a TV show in your own home, if he co-opted your local mail service to send you constant invitations from people you've never heard of, if he boasted about how many other people were going because he'd forced them to RSVP — well, would all that make you more or less likely to attend his shindig?" http://mashable.com/2014/01/10/google-plus-gmail/#:eyJzIjoiZyIsImkiOiJfMjExYm5kMnAwdHRrZWhhNWRrbXQyb2w1emhfIn0
