Custom feeds are not just for keeping up on the people and topics you care about. They can also be a place to engage with and build communities. 

To open your feed to contributors, add a hashtag to it — this can be anything related to the feed. For example, feed builder David Rush uses the hashtag #bathreads on Surf, ensuring that posts will be seen in his feed, no matter which platform the poster uses.

After adding the hashtag, people can post to your feed by starting their posts with that hashtag.

We recommend adding the hashtag to the feed description.
