I was trying to find out more about the symbolism of the DC flag but the website on DC symbols wasn't that informative. For what it's worth, I have heard somewhere (was it on a Capitol tour?) that the three stars represent the branches of government (executive, legislative, and judicial) and bars symbolize equality. This could be an urban legend or even some sort of ironic political commentary - since DC residents lack equal legislative representation in Congress (i.e., DC has no voting representative). For more on the DC voting rights issue and how the flag is used on both sides of the issue, see this alternate version of the DC flag and this DC license plate).
