Hooray! The single largest issue that bogs down better real estate Search is the hieroglyphical nature of the data between repositories (MLS’ primarily).
Many times cooperative yields far better results than competitive…but then the id, ego, and/or super-ego goes and gets in the way of things. Galen openly loathes MLS data normalization, so this appears to be a good thing. Looks like these current pillars of real estate Search have put aside their respective psyche’s in attempt to make real estate Search better for everyone.
