Letters of rejections

The Space Telescope Science Institute sent me a rejection letter. They said I was impressive. I guess I just wasn't impressive enough, eh? Why is it that there aren't more potential employers sending out formal rejection letters? It seems a tad rude. Is it costly? I received a post-card from the NewsJournal upon rejection and maybe a few email rejections. But seriously, if I took the time to craft a well thought out cover letter for you...can't you cook up a nice rejection letter for me? Dang, ya know I'd just rather be accepted than rejected. This positive thoughts. Yadda, yadda, yadda.
