Donovan Rypkema, author of The Economics of Historic Preservation: A Community Leader's Guide, a well-known and highly regarded speaker and real estate economist, began the PlaceEconomics blog back in April (it's included in the list of blogs in the left sidebar).
He started the blog because he came to the realization that "...I'm being a bit selfish with what I'm learning, that there ought to be a way to more widely distribute these great lessons. A blog may be it. So I'll give it a shot. While my clients pay me to come to their community, I nearly always learn more from them than they from me. And so I hope to translate what's being done in downtown revitalization, historic preservation, and economic development in any given community to a larger context."
His thoughtful posts include observations from his continuous travels to speaking engagements and consulting assignments as well as plenty of useful information.
