What is the "Peers" tab and how do I use it?

The investment goal: I own a stock. What similar stocks should I be looking at? I'm considering a stock. Which competitors and alternatives should I be aware of?  

The feature that achieves this for you: Peers. It shows you which other stocks are mentioned in articles which mention this stock -- leveraging the collective intelligence of our contributors. And it shows you which stocks people who follow this stock also follow -- leveraging the collective intelligence of our users. The results are remarkable.

How to use it: When accessing Seeking Alpha from a laptop or desktop (not mobile), in the search box at the top of the Seeking Alpha website, type in a stock symbol of interest. When you hit the symbol page, click on the Peers tab.
