Too bad it only works for transactions, not users.
LN is one of the better side-chain ideas to date, but it's still a bunch of I.O.U.s that have the bitcoin bottleneck. With LN, two people can reasonably send hundreds of thousands of transactions to each other, but hundreds of thousands of people cannot reasonably send two transactions.
And then there's centralization, off-network volatility, etc. issues as well. Side-chains are still not a viable fix for the blocksize issue.
