I feel a little déjà vu here. Ten years ago Karp led a NSF sponsored group with the mission of suggesting where the NSF theory group should focus its funding. The group held a panel discussion at the end of the 1995 STOC conference. Representatives from different subfields gave a short talk on the importance of their fields. After these presentations the panel opened the discussion to the audience.
Now instead of a physical panel discussion, Arora asks for a virtual one in a hope to draw from a larger base of people. Feel free to leave your ideas as comments on this post, on the committee page of the Theory Matters Wiki (edit password: tcs), or just by email to one of the committee members. Not everyone was happy with the last Karp report, so better to get your comments in now than complain afterwards.
