DR. HEY: I absolutely agree. We used to produce useful tools and give them to the users, but we found that they were not using them 6 months later. Even though we would show them how useful they were and they had all agreed, they did not use them. There is a real problem in engaging scientists. We have to produce tools that are as close as possible to the way that scientists are working now, but that at the same time give them an improvement. Advocates are needed, and it will be important to have some people showing how scientists can do great research with these tools.
