PLDI 2015 was a great experience. I had lots of chances to talk to people about interesting work and heard some very good talks, just like I hoped. I also got great feedback after my talk, which I really appreciated.
I also really enjoyed hearing the presentations at the SIGPLAN Townhall meeting. I was shocked at how much planning and work Steve Blackburn put in as PC chair, and he did a good job summarizing the lessons learned from the whole experience. Jan Vitek described the status of things like artifact evaluation, blind reviewing, and open access across the different SIGPLAN conferences. He also explained the results of various polls of SIGPLAN members on their views of these issues. Although there is a lot of disagreement, it's great that the SIGPLAN community actively discusses these issues. I think it's important for graduate students like me to pay attention, since some day our cohort will take a larger role in managing these things.
