What was everybody (on Twitter) talking about during this year's GDC? Game researcher Jesper Juul offers his annual look at the most tweeted highlights from the week of GDC, during which "pocket protector" was a surprisingly hot topic.

Back from Game Developers Conference 2010 and trying to get my bearings like everybody else.

On the heels of my twitter map of GDC 2009, here is a word frequency map of this year's conference. I think they give a decent picture of what was going on if you weren't there.

Monday: Day before GDC

Anticipation before the conference starts.

Tuesday: Tutorial and summit day 1

Social games loomed large, as did FarmVille, the iPhone, and indie games.

Wednesday: Tutorial and summit day 2

While social games and tutorials were still happening, this was completely overshadowed by the announcement of the PlayStation Move controller.

Thursday: Day 1 of main conference

The expo floor opens ("booth"), Uncharted 2 is big, and the award show dominates.

Sid Meier's keynote, parties, more expo booths. Harmonix, FarmVille. @pocketprotector wins the prize for most tweets.

Saturday: Final day (3) of main conference

Phaedrus' aka Will Wright's "surprise" talk takes a lot of space. Mass Effect.

Sunday: Post-conference

A great time, PlayStation move (again), Gabe Newell, time to go home. "See you guys next year."

Notes: Thanks to Mike Edwards for providing the captured tweets. I have deleted all occurrences of the quite frequent "game", "games", "gdc" and "rt" as they did not add any information. "PlayStation Move" on Wednesday is a 100 times more frequent than I would have guessed from going to the conference. This is probably because we are more likely to tweet news items than casual conversation. Made using Wordle.
