ThisNext  is a brand new social shopping  site that just officially opened last week. I have been using it for a little while now - it powers the Japanese Snacks feature you see on the sidebar of this site.
The reason I'm posting about it here on my food blog (besides the fact that my personal blog is in a state of dormancy at the moment) is that it has a number of interesting food related lists up there already. One is from Nate Appleman, the executive chef and co-owner of A16  restaurant in San Francisco. His list of Kitchen Essentials  has several knife recommendations among other things. There's also a list  from Regan Burns, editor of Chow magazine . There's my Japanese snack list  too! On the non-food side there are lots of new and unusual design oriented items listed, which I love, and lots else. Browsing around by tag can lead you to discover new sites to visit as well as products to check out. From the blogger perspective, making a good list on ThisNext could lead to new traffic to your site.
Sean at ThisNext has posted a short Q and A with me up on their blog ...if you are interested in my esoteric shopping habits.
Shelteriffic  has a nice review of ThisNext also.
