It was suggested to me that they be moved to another domain, and if there's consensus for that, I'd gladly host them on that domain. Either something like 911tribute.wikipedia.com or www.whatever.com, which I would gladly buy. Even so, I'd like to keep as much as we can, if it can be made NPOV.
Since you asked for references to specific pages, I went looking, and I'm now more ambivalent. I think what people have a problem with is pages like "William M. Feehan", which is just effusive praise and tearful reminiscence. But then there are also pages like "Brady Howell", which is a perfectly ordinary biography that I'd have no problem with at all.
I'm already on record that I support allowing biographies of anyone at all in Wikipedia, with no regard to whether their accomplishments or fame would merit their inclusion in a more traditional reference. As long as we take care with namespace issues, and those biographies are not mere self-aggrandizement, I have no problem with including any anyone cares to write--including those about 9/11 victims. But I also think that some people used these pages not for "biography" but for "eulogy", and that's not appropriate here.
I have nothing against eulogy--I created http://www.piclab.com/sasha for a friend of mine, for example-- and I would like to see a biography of him here as well. But I wouldn't put the memorial comments from my site into the article.
