It's also cool to follow people who seem interesting or knowledgeable. For instance, I'm a recreational diver who loves to travel & I enjoy diving with a buddy in sunlit, warm water with great vis. in my wet suit I'm following my polar opposite: a U.S. based tech diver who loves dark caves in cold water and dives in a dry suit. By seeing what he's posting & liking in my news feed, it takes me to a part of the board I normally wouldn't go & also increases my knowledge in a way that wouldn't happen otherwise.
Happy diving!
Well said! I find it all fascinating, especially the stuff I will never do.
