I personally am very much disappointed -- though I see why the decision had to be made (and am probably a small part of it, through complaining about one particular individual who denied important truths about my own faith community).
IDD's demise leaves me without a home. I'm an Anglican, as you may note above. We're part of the Reformation, but believe in the Apostolic Succession, the efficacy of the Sacraments, the importance of Holy Tradition in belief and practice... Where do I fit? I'm not sola scriptura, I hold to Grace as opposed to sola fidei, I'm not a follower of the Pope, and while we Anglicans come closer to Orthodox than to anyone else, I doubt that the Ancient Way is going to welcome an influx of Western-theology adherents as a part of their community.
Some of our doctrines fit in Liberal Christianity -- notably the strong focus on social justice and the primacy of the Two Great Commandments, taken as a guide to behavior. On the homosexuality question (for example, and with a strong caveat that this should not be used as a hijack to begin debating that) we hold that any act or attitude barring gay people who have accepted Christ as Lord and Savior from full participation in worship and fellowship is contrary to the "Love thy neighbor as thyself" command. This does not accord with the sin-and-necessity-of-repentance stance of most Protestants, Catholics, or Orthodox. But we hold firm to some traditional views, including the primacy of the Eucharist and the Apostolic episcopacy, that differentiate us from most "Liberal Christians" as the term is usually self-applied.
IDD is where I could respectfully agree with Catholics on some issues, equally respectfully disagree on others, and in doing so get at truths that neither of us had realized before about each other's faiths. But as with all things, the abuse of the forum led to its closure. And that's unfortunate, verging on tragic.
