Ah, thanks for that. It's not the funding stage yet, though, is it? As I understand it, there's still the interview stage until YC decides whom to fund.
We were really nervous about getting to the interview stage, despite the greatly increased odds of being accepted once you get there.
If I remember correctly, I didn't tell anybody, including my family -- the fear of telling them I was probably going to get in and then having to tell them I didn't was just too great.
Most startups choose (wisely) to keep the funding news secret until they can use it for press purposes.
