Hello. I'd like to introduce a popular service in Japan to the ProductHunt community. If you want to know what's going on in Japan, please follow me. This service is a popular social bookmarking service in Japan. It brings up news and other topics. Users can bookmark the articles and leave comments on them. Since many of the users are engineers, technical articles are often discussed, but it is a popular service because you can discover various interesting articles. You can add comments, and if you include extensions or other features, you can read the comments made on the article.
