We launched an overhauled Balsamiq.com this week and I wrote about the effort. In addition to doing interface design on the product (myBalsamiq mostly up to now) I also get to be the "webmaster." :) What that means in our small startup is doing the user research, interface design, visual design, and front end development. If you know me, you know that I dig getting to do more than one thing, so that's a win.
In any case, take a look and see how we evolved our little site. I'm planning to do another article on some the CSS 3 techniques I learned, but this high level blog entry will give you an idea of what I learned doing this project.
