Well the simple fact is you can't, as a typical user, "look" at a blockchain in and of itself. You are always going to be using some sort of application and the application is effectively a gatekeeper on eyeballs.

For example, steemit.com has started showing "featured posts" which have nothing to do with the blockchain, that is just whatever their company management decides users should look at, and those posts I believe get far more eyeballs as a result.
