Yelp: Leading The Way In The New Rudeness
I find this new model of having parties reprehensible. I guess it works like this: you invite 200 people expecting 150 to say yes. If 200 say, "Cool," you send emails out to 50 of them saying sorry: the party was oversubscribed. Maybe better luck next year.
Newest example is the Yelp SF party:
SF Partyto undisclosed-recipients, date Nov 29, 2007 7:57 PM subject Update on Yelp Holiday Party mailed-by yelp.com hide details 7:57 PM (55 minutes ago) Reply Hi there, Thanks for RSVPing for the Yelp Holiday Party and we apologize for the delay in getting back to you.
Unfortunately, we’ve reached capacity and therefore cannot add you to the final guest list. As you can imagine, we would have loved to have accommodated everyone that took the time to RSVP, but unfortunately due to space limitations and an overwhelming response, we filled up very quickly.
That said, we hope to see you in 2008, of course on Yelp, but perhaps even as a future member of our Yelp Elite Squad for whom we’ll have plenty of exclusive and more intimate events over the new year.
Happy Holidays,
Jessica T. and the rest of the Yelp team.
Aw! Blow me. Don't "invite me" if it's not really an invite, dickheads.

I find this pretty amusing. Perhaps they can take their next step into dating? They will ask 15 people out for you, when they receive a person agreeing, they'll revoke the dating invitation to all the others.

I agree. This is rude and surely will up your douche-factor in my book. If you invite somebody to a party, you should be ready to accept them when they say yes. Or deal with the disappointment if they can't make it. But saying, oh, never mind, we got enough people now, thanks for trying. That is not cool.
