I hope that one day there will be a more user-friendly iteration of Lightning that doesn't make it so complicated to get started. Channels feel like an invite-only system; I get their purpose, but they still feel like you are invited into some VIP club x).

I totally enjoy and support the general idea of Lightning though; low-fee micro-transactions from person to person (well, some of those are not so "micro" at all... xD). Awesome stuff, wonder what the next innovation will be. ^^
