Concur, on the source-familiarity. I got pimped on a source, I consumed the source, I wrote a Yuletide story for it -- in my case, I saw the movie after the Yuletide noms/signups were complete, so it was a treat and not very lengthy. But I could see myself signing up to write it next year.

Pimping is great! Even when I don't remember the slightest thing about what was pimped about that particular source, if I run across it on (say) Netflix Instant View, the name will ring a bell, and that bell will push it up the queue closer to the top.
