Thanks for the positive feedback but also thanks for constructive criticism. I appreciate both!
It seems most critique is about the top menu and about the market place. The menu is something I have been struggling with for a long time. I wanted it to display bigger on my iPad (nowadays a huge percentage of Pinside's visitors) but I also need space to extend for future menu items. And also allow for things like polaroid images to "stick out" and not go over the menu. So what I ended up with seemed the best option, considering these factors. I will dive back in at a later date to see if I can improve it, make it work better in some other way.
As for the market, I personally really like the new Marketplace view but also realise that not everyone would like the waterfall. That's why I also included the option to have single rows, or double boxes (option 1 and 2 in the 4-views selector). That said, I did notice some display bugs in those 2 views which I will look into asap.
I can understand the requests to "remember" your market search filtering options (e.g. turn off Ebay or change default sort order) and will work on an option to store these in a cookie or in your profile.
People who lost a lot of Karma, please PM me and I will investigate what happened. There could be some gains/losses but it should run into the millions.
All in all I think the update went pretty smooth, at least the site is still running
