Congrats to Brent Simmons on his retirement! This is an impressive list of apps to have been a part of. I’ve actively used all of them over the years, and a few I still do:

Along the way I worked on, among other apps, Userland Frontier, NetNewsWire, MarsEdit, Glassboard, Vesper, OmniFocus, OmniOutliner, and Audible.

I did a little digging, looks like I first linked to Brent in 2002, not long after starting my blog. I met him later at WWDC, back when it felt like you could meet everyone, although which year escapes me.
