Adultwork Devs really should be reading this \ asking us how to make the site the best it can be.
I suspect the mandate from AW Management is to make as much money as possible. There's no doubt a financial reason for moving everything to the new site.
They definitely read this site, as things in the past on AW changed after being noted on here. For example, someone came up with a hack to see hidden feedback, that lasted for a few days and got changed.
I can't think of what financial motivation they have for stopping us from indexing profiles; suggestions anyone? If there is a financial motivation, then it will happen.
