I recently took a cab into Anacostia, and upon entering from the 11th Street Bridge asked the driver if he came to the neighborhood much and what his perceptions of it were. He hadn't driven there in about two years, so I remarked at changes that I could point to: Anacostia Gateway, refurbished commercial buildings, cleaner streets, etc.
His response, although not a revalation, was interesting. He told me that in order for people to really recognize the changes in Anacostia, its gateways sorely needed to be addressed, especially at its most visible approach - the southwest corner of MLK and Good Hope:

He also said that although Anacostia Gateway was great, it is in the visual periphery (from this direction, at least), and therefore doesn't have the same effect on first impressions.

I'm sure that the corner will eventually change, but its "I look like a deserted failure" appearance only serves to scare people, retailers, and investment away. The AEDC's
Welcome to Historic Anacostia sign would better serve the neighborhood on a symbol of its emergent success than on one of misrepresentative blight.
