A bit late to the party here, but I'd like to echo the comments and thanks from other members of this forum, Mark. Yes, it seems that Facebook has made it redundant, but in its day this was a fine debating chamber, notable for its penetrating punditry on a wide range of matters. But you kept it (mostly....) civilised, Mark, and it was often an excellent place for good-humoured discussion, which was occasionally even well informed.
As others have said, Facebook is a very poor substitute. So thanks again for all your good work in running the forum Mark, and long may the website itself continue.
