One of the key challenges for Twitter to carry on growing, and become a truly mass-market platform, is to create things that help people over this hump - which also means mitigating an essential characteristic of the product. The contradiction is that the more that Twitter solves the on-boarding problem, the less sticky it may be. The less manual it is, the easier it is to make something similar.
