In the main home feed, we merge all the content types (post, question, discussion, article) in one place. The content you see on the main feed is generated based on the time they are published; most recently published content on the top of the feed.
However, you can filter the contents on your home feed based on their type, using the dropdown on the top-left of the feed.
Our premium and enterprise clients are able to use our Groups app, which leads to the customized feed for each user based on the group(s) that the user is member in. You can learn more here: https://community.tribe.so/question/5d24ad0fd71a193a557d3c52#answer-5d24d6df32350a6b1e2c5fa7100
