I've recently discovered the 1000Watt Blog written by Marc Davison and Brian Boero of 1000Watt Consulting. It's a great read for anyone associated with the real estate industry, and worth checking out.
A few posts I would recommend are "Shaking and baking old ideas" and "The blue ocean of real estate", a great reality-check/lesson on technology hype and trends via top-producing agents. You may also want to watch their video I'm not a lead, which has been mentioned in many RE blogs lately.
They've also created a really unique map of the real estate web 2.0 interweb - hyperlinked and categorized for handy reference. As of the screenshot below (Jan. 9th) they've got 85 sites and blogs listed. It will be fun to see this grow over time. Look for updates.
They even make it easy to submit your own site for inclusion on the map.
