The name Brent Simmons has been joined with famed Mac (and now iOS) RSS app NetNewsWire for so long, it's hard to imagine them being put asunder. That's exactly what's happening, though: Simmons has announced that NetNewsWire has been sold to Black Pixel, and that he won't be going with it. Instead, Simmons will move onto other projects after nine years spent working on the RSS client.
NetNewsWire started out as Simmons' pet project under his company, Ranchero Software, back in 2002. At the time, RSS was just barely beginning to make its way into nerd culture (some would argue that it's still working its way through) and NetNewsWire on Mac OS X was one of the first desktop RSS apps on any platform.
