I’m certain that the place holder for my photo should be a much better image than the one I’ve used. I don’t even have a self photo in a file on my laptop. Perhaps when I meet with you all someone will be able to suggest an appropriate image for me. Can’t wait!!

In the category of civic data aggregation & visualization, I really like EveryBlock. They aggregate and display (though somewhat light on the viz) as much local news, social feeds, and civic metrics as they can scrape. And they plan to release the platform as open source so anybody can use it for their own city.
