I think the most important component of web 3.0 will be for users to have individual choice of choosing open sourced content discovery algorithms that work in their best interest.

Web2.0 is characterized by companies building algos that maximize user time-on-siste, exposure to ads, men and convertion to clicks and purchases. More often than not, this is not in the user's best interest.

Transparent, open and immutable blockchains can allow for anyone to build user-centred content discovery mechanisms and storting algorithms, that users can choose and community devs can verify works as promise and/or improve upon.

It certainly won't be dominated by the top down approach of stakeholders deciding what users should get to see (which is the case for web 2.0 and the current state of Hive),but rather bottom up from what users and communities find valuable.
