With the OP here, I saw the thread title and silently went "thank god" to myself immediately knowing what this meant, having used PadMapper very extensively in the last year after moving to Austin. I knew it meant a good portion of ads being gone, but I was going to get much more qualitative results in finding a condo.
I really hope PadMapper can make up the volume but continue to have good results for people searching. It's a wonderful resource.
