The "Grand Parent" commenter - that is, the HN user "snowwrestler".
I thought it was "general public"
Snowwrestler in this context, I've always taken it to mean two comments above whatever comment says "GP" (grandparent/grandposter of current comment). But I've seen GP/OP used in slightly different contexts which is sometimes a bit confusing admittedly.
Yes, I always thought GP and OP were similar..
GP in this context is most likely the General Partners.
Serious question, why reply hours after there are several comments with an obviously wrong answer?
