As fun as the opportunity to reminisce about the likes of line rider was, I'm disappointed to see the omission of clippy, the wayback machine, livejournal, yahoo answers, something awful, google groups, xkcd, temple OS, stumbleupon, lycos, activex, toolbars, ytmnd, hypercam, winrar, Ted Stevens, slashdot and doubleclick.
Some of them are more deserving of a slot than others.
