From The Guardian:
Merriam-Webster, the revered publishing house known for its texts on American English, released today a sample of more than 100 new words it has granted entry into its Collegiate dictionary this year. Fully a fifth of them relate to technological innovation.
"Vlog" makes its debut, defined as a blog containing video material, as does "webisode", that is a TV show that can be viewed through a website.
Some old expressions have finally made it into Webster years after they were coined, courtesy of renewed digital interest. So "fan fiction" is traceable back to 1944 but the writing of stories by fans involving popular fictional characters has boomed through posts on the web.
Likewise, the use of "sock puppet" to describe a false identity used for deceptive purposes originated in 1959, but its proliferation on the internet has given it new life. And "flash mobs" (1987) - crowds that descend on a designated location to perform an event have now become so common thanks to email and text message, that the phrase has now earned its place in the dictionary.

All the "new words" mentioned in this extract were already in Wikipedia. Not bad for a source that is often criticised for being unauthoritative and unreliable. (I'm a Wikipedia fan, in case you hadn't noticed.)
