Suresh, Scott, and Lance have already announced the list of 78 papers accepted to STOC 2006. As Suresh points out, there's lots of cool geometry papers this year, and oh yeah, some other stuff, too. (I wonder if it's the same Santa Claus problem.)
PC member Piotr Indyk tells me there were 288 papers submitted to STOC this year, so the acceptance rate was 27.1% (or as Piotr actually put it, 27.083333333333333333%). This is the largest number of submissions in STOC history, but just barely—there were 287 submissions in 2002. This is also the second-lowest acceptance rate in STOC history, at least as far back as I have stats. The theory community's early-00s growth spurt seems to be holding strong. Here's the chart (also in pdf format):
SOCG results will be out Real Soon Now; stay tuned!
