Hi all. I also got rejected. This was my second time applying. The good news is I got other funding.
Just wanted to give everyone a heads up, though: last year I asked the SSRC folks if they had any feedback I could look at since I was preparing a new application, and they sent me a document with all of the reviewers' comments. As far as I know, they do not send you this feedback otherwise, but don't seem to have any restrictions on giving it to you. I actually found the feedback from SSRC some of the most helpful and constructive feedback I received from any agency.
So, especially if you are reapplying, and even if you're not, shoot them an e-mail.
Good luck to all those still in the running and to those waiting to hear back from other applications! Hang in there!
