There can only be one website...

[FireAza]

Probably eBay, where else am I suppose to find obscure random products for cheap?

Wikipedia, obviously. Unless one of the more reputable [and usually expensive] encyclopedia sites decided to become free and develop a forum.

I'd forge one beast of a website that holds all of the internet.

As in 1 home page and a gazillion subpages, all with their own function. Basically the internet under 1 banner... Hrmm.
Didn't anyone think of that one yet?

 

[Scorekeeper]

Wikipedia, with an honorable mention going to TV Tropes. Google would be useless; Facebook isn't particularly important (despite edging out Google as my most-viewed recently); Cracked isn't reliable enough; Grooveshark and Pandora, while valuable wouldn't top the all-important Wiki.

Forget Wikipedia, there is such a thing called a Library. It's a building that house alot of books (that what I did when it come to research homeworks before Wikipedia was invented).
OT- Eitehr Youtube or The Escapist (yes fanboy I know).
