Aggregation of the Revit Nation

There is huge amounts of data available to Revit users.  Some of you may already be aware of the portal slash blog directory slash aggregator site that I have set up at http://www.revitprofessionals.com/

Don Rudder has recently created a paper.li about Revit (and RTC) at http://paper.li/AYBABTM/1308511210#

Then there is the Revit Hate site that I have posted about previously, but happily there is also a Revit Love site that you can check out.  These sites bring together comments from Twitter and Facebook for easy reading.

Do you use a different Revit Portal or aggregator site?  Feel free to comment.
