An ecosystem, strong as a lion and wise as a Wolf, will starve without sheep and grass.
DeSo ecosystem is not just about project side and developers.
Where there is no grass there will be no sheep, and without sheep the Wolf will eventually flee.
If the sheep are the user and the project is the Wolf, then we still need a farmer to plant grass.
DeSo ecosystem will thrive if he finds a farmer who grows grass.

Why is DeSo's retention rate so low?
That's right, we don't have grass farmers in our ecology.
Compared with Web2.0, we find that advertisers are the farmers who maintain ecological prosperity.

一个生态，强如狮子，智慧如狼，没有羊和草也会饿死。
DeSo生态也不能只有项目方和开发者。
没有草的地方不会有羊，没有羊狼最终也会逃离。
如果羊是用户，项目方是狼，那么我们还缺一个种草的农夫。
找到种草的农夫DeSo生态才能欣欣向荣。

至此我们惊奇的发现，为何DeSo用户留存率那么低？
没错，我们生态中一直没有出现种草的农夫。
对比Web2.0生态，我们发现广告主就是维护生态繁荣的农夫。
