I'm not enjoying the new one. It's harder to navigate and search. I did find one book I was interested in, left a message for the seller (a mod), and never heard anything back. No cool toddler nursing book for dd and ds, oh well.
I just don't bother anymore. I won't bother selling anything here because there's no casual traffic, only people looking for certain things, as one would expect with a TP you have to specifically go to in order to see anything. There's no pull from the New Posts page anymore. That generated a huge amount of traffic and interest for me, both as a seller and as a buyer. And as a buyer, I'm usually not looking for something specific, just seeing if there's anything interesting.
There are plenty of other boards that offer trading posts with no charge for use.
