Source.

Choose a topic. It could be anything. Under the chosen topic, your photo or video will be ranked in a 5-tier color coordination Blue, purple, red, orange, and yellow.
Blue is the highest and yellow is the least. Your post will compete with other posts on the topic of choice. Depending on how many posts are under the topic, it will increase the upvotes to achieve blue. Creating a topic first will result in your name and photo showcasing above the topic, where users worldwide can click and see who the founder of the topic is.
Two goals when using Source, get as many posts under the blue tier as possible and create a trending topic for a chance for the world to see your name.
