[W]e’ve been having a lot of fun writing a series of small, self-contained web apps .. When we’re building these kinds of applications, which are often meant as low-ceremony apps targeted at a very specific purpose, or as service utilities, a lot of the time we don’t want to go through the hassle associated with a “normal” web app.
