    Hi, I have built my own website using Carrd and Raindrop at www.bbs4ai.com. My first intention is to create a social bookmarking service that allows users to add bookmarks of web pages with freely chosen keywords as tags, after personal review, in order to collaborate on business-to-business projects.
