Erm. I'm going to go... with Twitter.
And nothing of value would be lost.
[a href=http://davidtennantinplacesheshouldntbe.tumblr.com/]David Tennant in places he shouldn't be[/a] says I respectfully disagree.
OT: I also don't think killing facebook would work, everyone would just go back to Myspace. I'd kill TV tropes. It's function can be filled with wikipedia, and wikipedia doesn't eat ~3 hours of my life every time I visit it.
EDIT: I just realized that was on tumblr. However, Craig Ferguson uses twitter in his mail-room segments, and that's... something.
