Part of the beauty of the internet and HTML is its inherent serendipity – links lead you somewhere, and other links lead you somewhere else, beyond, anywhere. Yet, serendipitous as the web may be, few sites encourage this sort of haphazard exploration.
As developer Derek Powazek writes, "Serendipity powers the social web. It's why every website has a "share this" link. Serendipity is at the core of why Twitter is fun, YouTube is valuable, and everyone you know has a Facebook account."
In fact, argues Powazek, "we should be designing for serendipity."
Unfortunately, things like the bottom line, advertising dollars and other external forces mean web designers are tasked with keeping you on a page, not sending you off to discover something else. Even Powazek's examples, like YouTube's "related videos" section is inherently designed to keep you on YouTube's page. But the way it keeps you on YouTube is by creating a potentially serendipitous experience.
Nothing is going to change the need or desire to keep visitors on your page, particularly if eyeballs on those pages are your source of income, but adding the element of the accidental discovery to your site can make it even more valuable for your visitors.
