This is your reminder...
There is no algorithm that brings posts to your timeline. The only posts you will see under your Home tab will be either people that you follow, or the boosts from people that you follow.
BOOSTING IS THE LIFE BLOOD OF MASTODON.
If you read something that is interesting, funny, thought provoking, news worthy, or beautiful, then BOOST IT.
Hitting "Favorite" lets the poster know that you liked it BUT IT DOESN'T LET ANYONE ELSE KNOW.
Keep Mastodon alive. BOOST.
