We currently have more information available to us than any other humans that have lived on Earth and there is practically an infinite amount of things to do on the internet. What is there to do on the internet, I'm bored out of my mind.

Go to StumbleUpon.com and "stumble" categories that interest you. Stumbling is going through web pages that others have rated well. You can do this randomly or in specific categories like photography, cool pics, science, technology, blogs, art, culture, etc.
If you are into Science & Tech then TED.com is very cool! Click on "Themes" at the top of the page and then look at the list on the right side to see what they have in different categories.
I always have fun at Hubble Telescope pages & pics.
Wired.com is always fun too - lots of tech stuff.
I enjoy reading foreign newspapers (online) to get a different perspective of what's going on in the world.
What are you into? It would make it a lot easier to answer your question.
