I go back and forth on the lightning network. I guess I'll need to see what it looks like in practice, but I don't really like the idea that you have to set up a persistent communications channel for every transaction partner.
Still, it seems like it's been working fine on LTC, so there's every reason to believe it'll do well on BTC too. They definitely need to do something, because BTC was essentially useless when the transaction fees were high.
