On desktop (old Reddit), the follow button is on the sidebar (right). On a mobile device, the follow button is located on the right of the username. Your home feed will now include their content.
How do I find out which Reddit account belongs to a certain person? To see if someone is following me, go to their profile and click the button “follow friends” at the top of the page.
In addition, When you follow someone on Reddit, do they realize it? No, but they may search for it.
Finally, What is the significance of following someone on Reddit? Following is similar to subscribing to a subreddit, except that it refers to your profile page. Users may now post directly to your profile rather than a specific subreddit. If they follow you, any postings you make to your profile will appear in their front page feed.
