There are a few ways to tell Particle what you want to see, or not see.
Content Preferences: Go to Settings > Content Preferences to choose how much you'd like to see different topics and sub-topics. Fine-tune your preferences by tapping "+" or "-" for each topic. Click on the arrow to expand the list of subtopics. Here is a chart to help you understand how to best use this tool.
If a core topic (e.g. sports, politics, entertainment) has a full red circle, any green (or partially green) preferences under the core topic (sub-topics) will be invalidated. So in a scenario where you largely don't want to see sports, but specifically want to see college football, you'll want to do 1/2 or 3/4 red circle for the sports core topic> expand subtopics > green circle for college football > red circle for other sports subtopics you don't want to see.
Story Topics: On any story, tap the three dots and then "Topics" to see the topic classifications for the story.
More like this / Less like this: On any story, tap the 3 dots and hit "More" or "Less" to adjust your preference.
Topic Tuner: All new users will see our Topic Tuner as they go through signup, which lets you rate stories and train Particle on what you want to see, and what you don’t. But if you’d like to do it again, you can access the Topic Tuner at any time from Settings → Content Preferences → Topic Tuner to refine your preferences.
Follows: You can follow key people, places, things, by tapping on highlighted words, and tapping "Follow". You can also receive push notifications whenever they are in the news by tapping the Bell icon. You can also see what frequency to expect the stories in your feed (or in push notifications if you’ve chosen to) on the same screen:
Authors and Publishers: Just like with key people, places, and things, you can follow individual authors and publishers. See more about Authors and Publishers on Particle here.
