Plinky: Really? Questions? WTF, Over?

I watched Scoble’s thing on Plinky today.  I have to say, I’m not particularly impressed.

Here’s the quick run-down of the service: If you like answering questions, this is for you.  Plinky serves up a new question every day. You answer it, and can post it to your blog or a number of other services. Plinky hotlinks your answers and questions to any sort of related media (like a movie title or a book title).

It turns out that the guy behind Plinky, Jason Shellen, was behind Pyra (company that created Blogger) and helped create Google Reader.

My big question is this: how do you go from creating game changing bits of software like that to … Plinky?

Watch Scoble’s interview and tell me if you can figure it out. I’m baffled.
