It’s easy work to put features in a queue and have developers program away until each feature is coded. It’s hard to make a software product, where fit and quality are also needed to be successful.

There’s a long tail of businesses doing the easy stuff or trying to do the easy stuff faster. There’s really very little competition for businesses that do the hard work well.
