I don't have Facebook, so for some of my friends, the first news of my engagement was an electronic Save the Date that we had to send out a year in advance (we live in Colorado, and lodging in the area of our venue was already booking up fast). I received heartfelt congratulations from about half the people to whom I sent the Save the Dates, but some of the folks I would have expected to hear from haven't replied--it's been two weeks. I realize that it's not standard to reply to a Save the Date, but if someone I knew and cared about got engaged, and took the time to send me a Save the Date, I would at least say, "congratulations". Now, I realize it would be rude of me not to send them an invitation if I sent a Save the Date, but just curious if anyone thinks this is poor etiquette on my friends' part. It just doesn't sit well with me, and I'm now less enthusiastic to have these folks at my wedding.
