Oh dear! That was me in my post-DH hyperness! I'm soo sorry!!
That's what comes from being too embrolied in fandom. You think that everyone must have read the books by now, and you can no longer remember what constitues a spoiler.
Can't believe you avoided all spoilers even up until OotP! I didn't think that was possible at this stage. Good job! Just make sure to avoid fandom like the plague.
Again, lots of apologies!
