Micro payments as you listen (called streaming sats and boostograms) is one use of Lightning. Lightning, as a kind of Layer 2 technology on BTC is getting a lot of VC attention and pushes to put it into the real world. This is why bridging between Hive and Lightning allows Hive and all of us on Hive to get access to some of the investment being pumped into Lightning projects. Every time they manage to sign up a new retail channel with Lightning, Hive holders have very easy access to it. Hopefully that will get even easier if we build the kind of gateway I have into existing Hive wallets.
