In my experience FB is what you make it to be. It requires some curration effort but you can mold it to be useful. But you can’t just add, you’ll have to block as well, including ads - each ad source can be turned off.
For me, FB is the main source of news about local concerts. Sure, you’ll find about major ones anyway, but there’s no way to effectively track small ones. It doesn’t have to be music. FB is the easiest way to track niche local businesses, events, or groups of interest. Some of them even don’t have web sites and FB is where they post. Even when they have sites, you wouldn’t visit each of them every day to find out what is new and interesting and you’ll miss stuff.
