There are four buttons at the top of NotSobot: Positive, Negative, Questions and Random.
First, select a positive or negative mood to view posts. Next, you may type in your own question (or use one of the pre-bundled questions) and browse for posts only with that tag. You may also select “Random” to see posts selected randomly.”Questions” will be seen if you are not logged in to your Tumblr account.
NotSobot was designed as a mood filter to find the kinds of posts you like and hide those you don’t. To keep the site up and running, it uses the Tumblr API so that every time you view a post, refresh or change your mood setting, NotSobot sends a request to Tumblr’s database. By doing this, it actually “posts” the post on your behalf and updates the “likes” and “dislikes” for each post.
