Odaily Planet Daily News Vitalik Buterin wrote that L2 is a cultural extension of Ethereum, which points out that Ethereum is an L2-centric ecosystem, so you can freely build a sub-ecosystem with your unique functions independently, and this sub-ecosystem is also part of the larger Ethereum.

Diversity of participants.
