Discover interesting posts and accounts by following hashtags. Posts with followed tags will appear in your Home timeline on the web and all apps.

How to follow hashtags:

1. Log in through your server's website
2. Search for hashtag and click on it to see results page
3. Click on the 👤 + icon in the top right corner to follow the tag (click again to unfollow)

The web and most apps don't have a list of followed tags, but this will be in the next update. (iOS already has it, click # in profile)
