If a breeding species is scarce & vulnerable, keep it to yourself. If they're not, then who wants to know about it? Just discreetly record it for the atlas or whatever - the rest of the world doesn't need to be told.

That´s precisely the point. Lots of people want to know about it. I agree wholeheartedly with yourself, Twite and Pariah on "zero tolerance" of revealing nest-sites. Last year I got about fifty e-mails and phone calls from birders wanting to know where the local nesthole was. I didn´t tell any of them. (Many of them would be precisely the ones to criticise dissemination of information on rare breeders...except of course to themselves, which would seem to be permissible).
But aside from birders, who are after all hobbyists, there are others who "want to know". For example conservation-aware landowners, Birdwatch Ireland, the Rare Birds Committee. "Recording for the Atlas" is disseminating information. So is telling any of the above. There is no question of "fanfare", as I said, exactly four people knew of the GSW site last year near where I live. Only those four still know. And no more will know, as it´s on private land, and innaccessible. (I´ve no idea what happened at any other GSW sites in the country, I´ve never visited any. But I know highly critical birders who
have visited those sites, because apparently it´s okay for
them to have a shufti, but not for anyone else. I even know of some birders who went to a Wicklow nest-site to see it, then complained vigorously that there were
other people there too! Go figure...).
As for information-control, the OP simply wants to see a GSW in Ireland. Half of Bray know there are woodpeckers about; people have seen juveniles at their garden feeders in twelve gardens in three different areas of the town. Kids I teach, and people on the street, regularly give me "woodpecker-reports", from Bray and elsewhere in Wicklow. Should I swear them all to secrecy? What should I tell the twenty or so neighbours that have asked me about "that drumming sound"? That it´s "Classified"? It is simply not reasonable to suggest that people shouldn´t talk about woodpeckers in their locality, in their gardens, or on their estates. In fact it is important to raise awareness, in order to encourage people to both appreciate and fund conservation efforts. This doesn´t mean "revealing" nest-sites, but it does mean telling people, especially the young, that it is worth protecting the environment because there is a chance that biodiversity-loss can, in certain cases, be reversed.
In any case, I for one have put in hundreds of voluntary hours in the last two years monitoring GSW sites, not in order to tell lots of birders about them, but to inform the landowner and BI of progress. I could have spent that time rushing around the headlands of the country in search of rare (and pretty meaningless) vagrants, for my own amusement. Or I could have simply stayed in bed. Next year I probably will, in order to avoid being lectured to by people who haven´t done as much.
