That's because, as a downtown resident, I'm more concerned about the livability of the neighborhood rather than commercial statistics. Most of my focus has been on parks, community groups, and infrastructure/transportation improvements (jealous of the Houston bike-share program). Downtown Dallas has a long way to come, but it has improved a lot in the past decade and there are more residents taking an active role in its evolution.
We're experimenting with ideas that are successful in other cities and celebrating the small wins. Things like parklets, two-way street conversions, bike lanes, "glass box retail" and even busking programs do improve the urban experience. Out of curiosity, does Houston have grass roots organizations or city support behind these types of urban interventions?
Both cities could learn a lot from each other.
