Marvelogs is for HackerNews Power Users.
What is it? and How does it work?
You can think of Marvelogs as Tweetdeck for HackerNews.
With Marvelogs, you can query HackerNews contents in many ways and organize them in an easy-to-digest view.
For example, you can view 'Show HN', 'Ask HN', latest comments submitted to your posts, posts that are about Apple etc.
The results of each of your queries are added to a board. You can create as many boards as you like to organize the contents and each board can also have as many columns as you wish.
