Larry Constantine recently wrote The Open-Source Solution: If most commercial software isn't any good, why not use a more communal approach?
Open source may be superior in producing robust, reliable code. It can hold its own in providing functionality. But its weakness remains usability, which increasingly is the battleground for competing programs.
He writes that the joint efforts by a million programmers increases software reliability, but overall usability hasn't been reached yet, especially as new functionality is added. Joe Dolson brought this topic up for discussion, and it appears as though the consensus is that in some cases, usability has been accomplished. They point out WordPress as an example. What do you think?
