I think social media is great for the hobby. Different people prefer different platforms and no matter what platform(s) you use, you can find others with similar interests and share information and ideas. Before social media, we were limited to a few books and a handful of local reefers the help us learn and make decisions for our tanks whereas now, we can share information and experience with an exponential number of people across the world. Just like anything, the user has to look at the source of information and decide if it’s credible info or not and that can be based on looking at their tank, years in the hobby, if they perhaps work at an LFS, etc... I also think a lot of people lose track of how much time they spend on social media and can end up spending more time than intended on it. For me, shutting off notifications is helpful. I only go onto social media when I am looking to kill time or if I’m searching for information.
