New in PLDI 2009 External Review Committee (ERC) –51 members (printed proceedings are missing names) –Nominated by program committee as experts in their own areas –Bid on papers—just like the program committee Inspired by ISMM 2008

Paper Submission Double blind without compromising paper –Authors could submit TRs etc. which I forwarded to reviewers as needed –Authors could reveal their identity in their rebuttal if needed Authors indicated conflicts with PC and ERC members

Paper Reviewing 196 paper submissions (a record!) 3 PC and 1 ERC members reviewed each paper –X reviews: 310 –Y reviews: 371 –Z reviews: 110 Obtained additional external reviews if a paper had too few X/Y reviews

Rebuttal/Discussion Period 10 days between rebuttal due date and PC meeting I acted on three categories: 1.Not enough expert reviews Obtained additional reviews 2.Strongly conflicting reviews (AD) Initiated online discussion ~180 messages total 3.Strong review was external Initiated online discussion
