Facebook is a great tool for ministry. Outside of going to school campuses, there are very few places a youth minister can go outside of the church and interact with more students. However, Facebook added a setting which they made default that is proabably hindering your use of facebook as a ministry tool without your knowledge.
If you go to your feed and click most recent, most people assume that is everything posted by every one, but that is most likely not the case. Click the disclosure triangle next to “Most recent” and the go down to “edit options.” Now look at the field next to “show posts from:” Unless you have changed from the default you will notice that “Friends and pages you interact with most” is selected.
For a while, I had been noticing that I wasn’t seeing baby pictures from my extended family or my Church’s main group updates, but figured they were getting lost in the feed. These were groups that, though I wanted to see the information, I didn’t interact with very much. All you need to do is change the setting to “all your friends and pages.” Then, just hide the people and pages you don’t want to see in your feed.
