Jamie,
I will start by saying if you are giving out a cold beer I will be right beside you.
I am new as well, and I am always willing to share information. I guess I see two sides to this.
1) yes if someone says a specific spot is very good, it can get overrun.
2) yes I bet most people found a spot by talking to someone else.
The bottom line is you have got to know and trust people before people will be willing to give up information.
But I will give you my .02
THERE ARE NO COD AT THE ISLES of SHOLES off NH.
Hell fishing is a social sport.
Have FUN! and move closer to the ocean!
