A great blog to follow right now is the official 2010 Census Blog. This blog will answer just about any question you might have had about the census. Wondering how they'll count prisoners? Why they ask for a telephone number? Who gets a mail in form and who will be personally enumerated? Will the census returns be kept? These and many other questions are answered on the very active blog. The blog has presented multiple maps as well. They even gave a shot out to the genealogists of 2082! I really recommend following this blog.
