An Early Eulogy for RSVPing

I think that RSVPing is dying, in part due to things like Evite and Facebook events (where you can change the content of your RSVP every day if you like, and where you can RSVP up until the event itself), and, more than that, to our last minutely spontaneous, waiting-for-a-better-opportunity culture. My personality is not well suited to this century. An RSVP is a commitment--I will attend this event, even if an event I like more comes up. It seems like it isn't well suited to the types of events that people commonly attend today--our events are fluid and amorphous, and I was born without the flexibility gene. Alas.
