Unfortunately it seems to be a dying tradition. I always did send thank you notes - driven home to me as a kid by my mother - and I still do. Even now if it's only in the form of an email, I still do it. However, on the recipient side, I almost never get any kind of response. Rude and sad, all wrapped into one! Definitely, change is not always for the good!

I do believe that the posters ages here are showing too!
