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.
This strikes me as exactly right. Some of the elements that make a product slippery to begin with are the very same things that make it sticky with continued usage. Twitter has a very fine line to walk between those two worlds.
Ditto. The more mass appeal Twitter strives for, the less appeal it has for its niche users.
