Are you looking for good blogs in the real estate field?
Here is a good opporunity to get a great sample.

An initiative called 'Carnival of Real Estate' runs in The US under the summer.
The first post is from Zillow and could be found here.

"A Blog Carnival is a weekly summary of the best blogging posts on a given subject that appeared in someone’s blog during the previous week. A different blog hosts the carnival each week, so it brings bloggers writing on a given subject together." www.carnivalofrealestate.com
