Sally Kerrigan, on A List Apart:
When you write about your work, it makes all of us smarter for the effort, including you—because it forces you to go beyond the polite cocktail-party line you use to describe what you do and really think about the impact your work has.
Totally agree. I also find speaking in front of people helps too. Defending what you’ve built goes even one step further and can really begin to solidify vision or break it down completely.
