When we built the Blog Builder, the timing was pretty perfect, as blogging was about to hit it's second wave of popularity, this time with the non-early adopter crowd. We were pretty excited to build it, which explains the two-month gestation period.
My initial role in the project was to work with engineering and figure out how the tool should work. It went smoother than any of us had anticipated. Now that we're three development cycles in, I'm doing the interfaces for the new features, their design, icons and user template design/coding.
