I have no problem with FB groups, I really don't. The more the merrier. My point is that there are still active groups here on the DIS (though you are right, some cruises more than others).
You know what's funny about this is that I think that there are a lot of people on FB that have no clue that the DIS even exists. On our Southern Caribbean (like I said, it was fairly active with over 20 cabins), we passed a number of people in the hall as I was dropping off SWAG into an FE with quizzical looks at the cabin with an FE hanging there trying to find it on their printout and saying "why are there all of these cabins that aren't on the list!"
