@whatsup I've tried doing the comment thing to keep track of posts, right now i'm embedding JSON in transactions, see my post where I extract the transfers from steemdata using node.js. I plan on creating web page to display bookmarks. send to @msteem. Replace link field with your bookmark.
{"type":"bookmark","action":"add","version":"00","link":"https://steemit.com/steemdata/@furion/roadmap-for-steemdata-2-0-help-needed","comment":"nice to have"}
