Brett Terpstra is now an independent developer and writer:

Monday will be the start of increased focus on existing projects and attention to new ideas that have been bubbling up. I’ll be writing, including finishing my tagging book and working on the children’s book. I’ll be developing Marked (starting with the App Store version) and adding a couple of smaller apps to the App Store list. I’ll continue blogging, which brings me to a final request.

If you’ve ever played with OS X automation workflows, Automator, scripts, or TextExpander snippets, it’s likely that you used one of Brett’s tools. Brett is the developer behind Marked 2 (one of my must-have Mac apps) and I’m excited to see what he’ll do next.
