#feditip for newbies, especially the ones who post a lot of politics stuff: use the CW or "Content Warning" feature if you want people to boost your posts.
For example, if you're posting about American politics, you might CW with the subject line "American politics" or "USPol" for short.
Using CWs has been part of the established culture here for years, and people generally don't boost unCW'd politics posts. If you think something's important and want to give it visibility, use a CW.
