Here's a very interesting interview of Jason Fried (of 37signals) by Walt Mossberg. It's from a conference on innovation in business. Jason explains how 37signals' business model helps them avoid the pressures of feature creep and how that makes his product a success. He emphasizes the use of the word "No" in developing software and trying to please everyone is the road to mediocrity. He comes up with a fitting analogy using Italian restaurants, but you'll have to watch the interview to hear it. The interview goes on to examine how feature creep affects the success of open source.
