I do have a FB account but their FB page is just a random pile of useless chaos. It is pretty obvious most posters have never read what anyone else said, they just post.
The structure of Facebook is totally unsuited for organizing information in a topical way and especially for saving information you might want to refer to again. It's just people talking about themselves or complaining about this or that. There is little or no actual discussion. It's a bit like what we would see here if they eliminated the subforums, threads and topics, and just showed all the posts in one long list in the order they posted.
I think, frankly, elimination of game forums is done expressly to suppress coherent thinking and organized discussion (and sometimes criticism) by burying it in the chaos.
All they really want is a place to make announcements.
