While I don't speak for my employer, the Sunlight Foundation, I am proud of many of its projects. There's a new one I think many readers here might especially like. It's called Scout; it searches through proposed state and federal legislation plus federal regulations and more.
Here's it searching religious liberty. And if you make an account, you can be sent updates. (Do.)
I think it's pretty clever, especially if you're concerned about the a wave of similarly-themed legislation coordinated across state houses nationwide. (I can think of examples.)
Here's an intro video where my colleague Eric Mill describes Scout's features and how to use it more fully than I have described.
