Well, it's not that, not for me. It's that event planning and invitations now happen exclusively via FB.
FB already separated the messenger from the main service. I'd love to see them spin off the event invitations into a separate service, too. That I would happily use.
Argh, this is one of our problems. Evite is a perfectly good system for invitations and event planning, in many ways better than Facebook events, but it is difficult to get all the Facebook-only people to use it. It sends invites, updates, and reminders over email, which is apparently Not Done these days.
