As you have probably seen on all the blogs out there, today is Terpstra Day. Like everybody else out there, I would just like to wish Brett a happy birthday. Without Brett, my whole Apple experience would honestly not be as enjoyable. nvALT, Marked, Markdown system services, his podcast Systematic, and the iOS text editor chart are all the products that Brett has created that I used in the last week.
Take a look at Gabe's post at Macdrifter to see if you use anything that Brett has graciously provided us with.
