Some points in reply to the post by Millsy:
For me it is always a 50/50 call. Try to prevent overcrowding at a good spot, share that spots success with my mates. In the end I tend to go with Craigs comments. Give a general area but not down to the last gps point. (easy for me as I don't have a gps

) . Also, most of my spots require an intimate knowledge of the sea floor and just where to anchor, 15 meters out and you will catch only weed.
We are Apathetic but the 'Beach' is probably not a good analogy. They raised $2.2M out of 4.4m people, about $0.50 each. Legasea raised $400k out of 600k of fishers, about $0.75 each. (But yes, still way to low.)
Re catch and release - I know that it works in some other countries and in some cases spectacularly so.
However I believe most strongly that introducing catch and release areas here in NZ, particularly in the salt, will backfire and bite us all in the arse.
The peta people out there, and their numbers are growing rapidly, already look at anglers as cruel and evil people, but they have always been defeated here in NZ by the attitude of the NZ public that fishing for the table is ok. Make salt areas catch and release and you remove that protection and we become in many non fishers eyes 'Blood Sport' monsters, up there with English Fox Hunts and Big Game hunters. Torturing fish for our own entertainment.
The argument used will be that those fishing for the table it really is all about the fish, but those fishing only for the 'fun' it really is all about the fisherman.
Lose the public support and we are stuffed.
Finally, I think that in the spirit of full disclosure, I am not a salt water flyfisher.....yet.
I tried it 25 years ago but to no avail, but back then there was no fishing.net from which to learn.
I am looking at a Redington 10 - 12 wt combo, but still in need of funds. Crowd funding anyone.
