What is Relevance?

Question for the masses: What is relevance?

What I’m trying to get at is, what provides relevance to you? Is it your friends, Page Rank, a recommendation, or something else? I’ve been thinking about this a lot lately in relation to the blogosphere/news. Why do you read what you read? What if there was something that could recommend things to you that you might enjoy based off of what you define as your relevance? Would that help or hinder you in your online information endeavours?
