It is very similar to Twitter, except the network is “anonymous”. (Also see: Is Yik Yak Really Anonymous?) Posts are called yaks (not tweets). Yaks may be engaged with (upvoted, downvoted, or replied to) by anyone in a 1.5 mile radius (via GPS coordinates).
Yik Yak’s main features:
- Peek. This feature allows people to see what yaks are taking place anywhere in the world.
- Upvote/Downvote: Posts (yaks) are upvoted or downvoted. These are essentially user ratings on a yak.
- Yakarma. This is a “karma score” aimed to measure the active success of a user. Yakarma is primarily affected by upvotes on your yaks. A more thorought description is available on Wikipedia’s Yik Yak page.
