According to the link below, we should expect an email by 10PM PST (about 25 minutes from now). I remain optimistic that YC would at least let people know that their applications were rejected rather than just ghosting them.

edit - the deadline passed, no email. Assuming that's rejection. I highly encourage YC to at least send automated emails to applicants who were rejected in future cohorts so there's zero confusion for anyone.
