It was the most overwhelming of all the cons I've ever been to, even though numbers-of-people-wise it wasn't quite so large. That being said, conventions like Norwescon have large sub-groups that I'm not particularly interested in, whereas World Fantasy was packed, PACKED with people I know, or want to meet, or otherwise want to talk to. It was all very, "holy crap, I know everybody in the entire world."
I added book #2 to my collection of "books in which I have specifically requested that the author sign and use the personalization to insult me", which means that it is now a Thing I Do instead of just a one-time attempt to let Scalzi get back at me for harassing him through most of Worldcon.
I got a ton of free books, bought some books, enjoyed readings (You want to pre-order N.K. Jemisin's The Hundred Thousand Kingdoms), and even served on A Panel that went well enough, I think. (I enjoyed myself, despite being terribly nervous when I first sat at the elevated magical panelist table. As far as whether it was a good panel or not, I think you have to ask the audience.)
One of the panels I attended resulted in a) the unveiling of the Science Fiction & Fantasy Translation Awards, to give prizes to SF&F that has been translated from other languages. www.sfftawards.org b) My purchase of a Haika Soru title, Usurper of the Sun by Housuke Nojiri. I'm nearly finished with the book now. It's very hard SF and the novel itself was written with a different literary aesthetic than I'm used to, which is a nice change of pace.
I'm still in post-con recovery mode, since I spent most of Sunday feeling hungover and tired. At the end of Sunday, I missed all the parties due to a ridiculous high fever. I slept almost all of Monday, except for being marginally awake during the Seattle-Bellingham drive.
In non-con news, I will apparently have a job after moving to Seattle, even if it is still retail. Yes, boo-hoo, whatever. I'm relieved that I will be able to pay my rent and bills.
I'm also doing NaNoWriMo, but I think we will all be happier if I don't talk about that here. At least, I will be.
