@danso thanks for the feedback on data.gov. I'm part of the small (3 person) team that helps to manage it. If you have a moment to chat I'll see if I can reach out to you to see if you'd be interested in participating in some more in-depth user research in the future. Folks can also always leave feedback via email, github, twitter, and other means - https://www.data.gov/contact

The Federal Data Strategy will also be opening up for comments again in October - https://strategy.data.gov/feedback/

Data.gov and Federal agencies use the same metadata standard (DCAT) that Google Dataset Search is using so much of our metadata is also being syndicated there.
