+ For those of you who enjoyed the recent "Firefly" shout-out on "Castle," Nathan Fillion announced on Twitter yesterday that "Buffy" fans have something to look forward to on "Castle" as well. Hopefully Rick Castle doesn't start blinding characters in a tip o' the hat to Caleb.
+ Also in Twitter news, you can now follow Neil Patrick Harris, who, perhaps unsurprisingly, is pretty funny.
+ The Penguin Books website has a cool new interactive feature where you can see the note cards upon which Vladimir Nabokov wrote his last novel, "The Original of Laura," which was completed recently by Nabokov's son.
+ Speaking of penguins, scientists have discovered that these awesome water fowl are evolving at a rate two to six times faster than originally thought. You know what that means: penguin overlords by 2012. Sure, we'll all smell like herring but that's a small price to pay for perpetual formal wear, don't you think?
+ Here's a cute interview with Katee Sackhoff in which she talks about her new role in "24" and also her theory on what happened to Starbuck. She also shares an oddly disturbing but completely believable story about Edward James Olmos.
+ It's a big day for Johnny Depp. It's been announced that he'll be earning roughly $38 million to play Captain Jack Sparrow in a fourth "Pirates" film, making him the highest paid actor in Hollywood. And he's People Magazine's new "Sexiest Man Alive." To which I say, well, duh.
