There’s a great interview with Wil Shipley at the DrunkenBlog, with a nice treat at the end (a history of UI design for Delicious Library). Wil has his own blog which is geared more towards programmers — but the interview isn’t really about that.
In drunkenbatman’s interview with Wil they go into why Wil left (or was asked to leave) The Omni Group; his founding of Delicious Monster with Mike Matas (and Mike’s decision to leave for Apple); the success of Delicious Library; Wil’s troubles with depression; Cocoa programming; and some great advice for ISV entrepreneurs. It’s definitely worth the time investment to read it.
