Your point about the science & whether information should be free, though, I totally see. Though... if they really thought so, why don't they just release the darn code already! Information doesn't want to be free, for them, information wants to be profitable for your weird libertarian corporation!
I did enjoy Infoquake though I just mocked it in a friendly way...thanks for the rec!
Here's my review - [blogs.feministsf.net]
So yeah, it's a marketing category that doesn't always hit the mark.
About the creepiness of adults reading YA books or books with young protagonists, I see your point, and have always thought for example that a huge amount of adult men fetishize characters like YT from Snow Crash in a not very healthy or well thought out way. On the one hand it's good they can think of a girl as a cool protagonist. Yet I do think there's an ick factor. I thought Stross exploited yet made fun of this exact issue, with his Wednesday-Adams-ish goth girl character in Iron Sunrise.
On the other other hand, I like reading books with kids as protagonists. I would point to Peter Dickinson's books, or Nancy Farmer's recent dystopian YA book House of the Scorpion, as great examples of YA books.
Did you read Spook Country? It had a really good dreamy poetic feel to it.
