Editor's Notes
- Welcome, and thanks for coming out this evening.\n\nI haven’t had the pleasure of meeting many of you, so I’d like to start off by introducing myself so that you have an idea of where I’m coming from.\n
- My formal education was in biological engineering, but I’ve always had an interest in information technology. \n\nMy first job out of school was working at a DNA lab helping to build custom software used for automated sample tracking and profile extraction.\n\nMy current job primarily involves eliciting requirements, driving stakeholder consensus, exposing risks and dependencies, defining the nature of user interactions, laying the groundwork for information architecture, and generally laying the tracks out in front of our developers so that they can proceed unencumbered.\n

- I’m not a developer, but I have a natural curiosity and want to know how things work on a conceptual level.\n\nI’m here to talk about things I’ve learned, trends I’m seeing, and experiences I’ve had.\n\nMy goal is to make sure that everyone here leaves with something tangible that they can use, or a perspective that helps them think about things a different way.\n

- Is this Noise?\n\nDepends on the context of the audience and how the content is delivered.\n\nIf you are already in a particular station, you probably see a “you are here” symbol on the map.\n\nYou are being exposed to this because you need to figure out where you are going, thus the risk of losing the reader’s attention is relatively low.\n\nZoom in on a region\n\nThis map emphasizes the different lines as well as the stations on each line. Also important are the zones crossed, which are shown subtly as alternating gray and white regions.\n\nAn interactive version would allow for reduction of clutter. Thinks like bicycle parking and car ports would only be toggled on by those who need that information.\n
