I believe this site would be more effective if it made a strong case why media funded by taxpayers is important. While the site does have a “Why” section that explains why individual actions for this cause are impactful and also encourages visitors to share “Why” public media matters to them, it lacks a strong argument why this should be funded on the call to action.
People who visit this page already understand the need for curiosity and educational programming. What would be important would be to show where money goes and the impact it creates. Because if you have to ask why education is important, you're not going to care about PBS/CPB in the first place.
