Big Questions is taking a break in 2015.
It has morphed into something a little different, but something I think you may be interested in following. I will not be using this site for this new venture, but have created a new one. On this new site I will update the content monthly, or more often, and include reference materials, links to sites you may want to read, and generally manage the process of keeping the flame burning, so to speak.
The new site is UU Perspectives on Faith.
Check it out.
