I made a Pottermore account. My intensely hilarious, randomly assigned Wizard login name is MidnightSparks379.
Pottermore is... odd. Still in beta, the site allows you to sleepwalk through the first Harry Potter book, on a Greatest Hits tour of the chapters and events of the story. It's sort of a game? Mostly you just click through Flash screens of paintings where everyone is either in shadow or has their backs to you.
When the account-creation process began, I was excited to learn that I am magical.
I had always suspected that.
Riding sidecar to Pottermore's on-rails novel summary is the notion that you're a Hogwarts student as well... so you have to collect items, buy supplies, play potion/dueling mini games, and be Sorted into a House.
I did not game the system; I got Slytherin.
Which is totally the House I wanted, so bully (literally) for me.
The "Welcome to Slytherin!" speech from your unseen Head Prefect is HILARIOUS. I am suitably amped to be in Slytherin House. We're currently ahead in House Points, naturally.
The real reason I wanted to check out Pottermore was to read the snippets of behind-the-scenes material from J.K. Rowling that has been worked into the site. I hope she finishes that encyclopedia she's been working on, because I could kill a lot of hours poring over the unrevealed history of McGonagall's tortured love life.
