Developer or Software Engineer? Can it influence your work?

ctrahey writes: Many of us disregard the impact of our titles on various aspects of our lives, both professional and otherwise. Perhaps it's appropriate to ask two questions about the difference between a couple titles familiar to the ./ community: Developer vs Software Engineer.

1. What are the factors to consider in the appropriate use of the titles?
2. (more interesting to me), what influence might the use of these titles have on the written code?

Have you observed a difference in attitudes, priorities, or outlooks in talent as a corollary to their titles?
