Going forward, the two sites will be simply known as Wirecutter:
With The New York Times Company powering our efforts, we realized that the best way to help our readers is to combine all of our coverage into a single site in order to find high-quality reviews on the things they need. We don’t want you to have to think about which site to go to in order to find running gear, or waste time thinking about where our recommendations can be found for learning & STEM toys. The existing guides that you’ve come to know haven’t gone away—you’ll be able to find them all right here, with plenty of new ones as well.
The new site looks great and it's certainly a fresh coat of paint. I'm glad to see the sites realized the arbitrary line in the sand between product reviews made no sense to readers.
