Blogging Grows Up by Farhad Manjoo (you can access this article by either having a Salon Premium account or by getting a free day pass).
We met with Farhad during the BlogOn conference last month to sit down and answer his questions about our products and Six Apart. I enjoy talking about the company because it forces me to think about how we've evolved and why. I think Farhad did a great job capturing the reasons why we built the tool, changed the licensing and why we want to grow the company (and the mistakes we made).
By reading old dollarshort.org and movabletype.org entries, Farhad was able to capture the story of Movable Type's roots in a way that I'm not usually able to articulate in interviews. I've told the story of Six Apart so many times that I, sadly, phone it in sometimes. Reading Farhad's piece, I actually felt like I was looking into the company as an observer -- it inspires me to go back and read internal weblogs of ours and old dollarshort entries.
The story of Six Apart has humble roots, but I'm really glad we're out of that apartment.
