John Gruber interviews Brent Simmons. NetNewsFireball? ;) In any case, a cool interview.

Brent Simmons is the author of NetNewsWire, the runaway smash-hit RSS news aggregator for Mac OS X, and the founder of Ranchero Software, which he runs in partnership with his wife, Sheila. Brent’s personal weblog is inessential.com. I interviewed Brent via email, and our extensive discussion covered a wide range of topics, including: Apple’s treatment of small Mac developers; deciding which features would separate the Pro and Lite versions of NetNewsWire; Brent’s previous experience working for UserLand Software; and much more.
