I recently attended (and presented at) the Researching New York Conference at SUNY Albany.
One guy is promoting the New York State History Blog: http://newyorkhistoryblog.org/ which looks to have some neat-o stuff. It's just about as random as this place, but limited to New York History, and includes call for papers and other content. he claims it's updated a couple times a day.
I attended a presentation on Joseph Smith and the translation and printing of the Book of Mormon. The three presenters are also editors for the Joseph Smith Papers, which also has a website: http://josephsmithpapers.org/
Both of these links have been added to the New York Quadrant as well (so you know where to find them when this post disappears).
