Speaking of charts, look how many more babies were named Finn last year than, say 2006. 1081 vs. 590.

The next graph is popularity in the US - i.e. Finn was the 457th most popular name for boys in 2006, the 300th most popular in 2010. Before 2000 it wasn't in the top 1000, so the Social Security Administration doesn't give us the data.
Back before we were even pregnant, I started playing with the website and following the blog of Laura Wattenberg - a baby name data analyzer. I still do, even though I'm not planning on naming any more babies, because it's often fascinating. If you read Freakonomics and liked the baby name chapter, you'd like this stuff. Come over for dinner sometime, and I'll let you look up your name in her book. Her most recent post said that her readers had predicted that FINN would be the fastest rising baby name of 2010. It wasn't - not even one of the five fastest rising - but it caught my attention.
In case you're wondering, no, we're not people who picked Finn's name because we were sure it would make him a unique and special snowflake and who get mad as it gets more common. We just wanted something rare enough that he wouldn't have to use his last initial in class (ahem, Katies born in the late '70s?). If we've caught a rising trend and he won't have to spell his name for people, and no one will have to agonize over whether to address his correspondence to Mr. or Mrs., I think that's great. The quote from the blog that caught my eye was "More than anything, this sounds like a class list from a Mommy-and-Me gym class in a fashionable upscale neighborhood." Reminded me of the article from a while back that listed Finn as one of "the best names coveted by style-conscious parents." This amuses us. Sure, we're educated. We have Lived In New York. But at root we still think of ourselves as Midwesterners. Slobby ones. But Finn, apparently, is destined for greater things, or at least will be able to pretend to be without changing his name.
Graham is also on the charts above, although he hasn't been getting the same kind of press. Graham held steady in numbers and popularity for years, but has been climbing the last few. But I don't think he'll have to use his initial after his first name at school.
Your bonus for wading through/past the above: a story from Finn, to the best of my memory and paraphrasing ability.
F: I'm going to go and visit the chinchillas. In... where do chinchillas live, Daddy?
J: South America.
F: I'm going to go see the chinchillas in South America. They are very soft. And very delicate. You have to be very careful with chinchillas. And my airplane will go fast! Faster than a bullet. Faster than a bullet! And then I will go to Africa. To see the animals. And they will not bite me. And I will stay in a tent. They will not bite me because I will not try to ride on them. And then I will go to Japan. To see the train. The train called... what's the train's name, Mama?
K: Hiro?
F: ...Hiro...(looks doubtful)
K: Anpanman?
F: The Anpanman train. I will buy another Anpanman train* for my baby. And it will (various things, involving going very fast, all directions, etc., etc.). And then I will go to Florida. And my airplane will go SO FAST.
K: What will you see in Florida?
F: Weeelll, I will go to a meeting. A three year old meeting. All of the three year olds will be there. But not the four year olds.
*Jonathan got the boys toy trains as souvenirs from Japan. Finn's was Thomas, Graham's had an Anpanman face.
Covering the above destinations probably took 5-10 minutes. I forget where we went from there, but it was very enlightening.
