During the past year the SIGACT Executive committee has considered the issue that the STOC conference no longer attracts a large segment of the theoretical computer science community. Lance Fortnow wrote a proposal for restructuring the STOC conference to focus on bringing the theory community based on the model of large non-CS scientific conferences that accept all reasonable submissions, with many parallel sessions and plenary and invited talks. You can read the full proposal here.
The proposal had some support and some opposition in the executive committee. We did decide to circulate the proposal to approximately thirty members of the theory community. You can read many of these responses below.
Based on the responses, the SIGACT Executive Committee decided to start with a mild change, increasing the number of allowed submissions from about 80 to 90.
