Ben Wollman proposes an interactive branding strategy to establish Walnut Street in Philadelphia as a premier destination. The strategy includes creating a website that serves both local residents and tourists, highlighting the area's shopping, dining, attractions, and events. It also allows businesses to connect directly with consumers. Key tactics are developing neighborhood maps with "green footprints" icons, installing information kiosks, and creating an e-newsletter with store coupons. The strategy aims to bring online and offline experiences together cohesively under the Walk Walnut brand.
