I have been without Facebook for about a year now, and the one thing that I really miss are events. On the one side, there are a lot of events that go over my head simply because they are advertised solely on Facebook. And while I know I cannot do anything about that other than having a Facebook account, what I also miss is a convenient way of managing my own (social) events, being able to send updates to my guests, changing the event details, etc.
I feel like Doodle covers part of it, but I've always used it in a formal/professional setting to schedule meetings, and I think that a Doodle invitation will be perceived as such. I wonder if there is an alternative closer to Facebook events that allows me to manage my (social) events?
