Closed source vs. open source

A column at ZDNet focuses on the difference. “What both sides ignore is that
[closed source] and [Open Source] serve two very
different purposes for two
very different types of
developers, and there is a
place for both within the
current IT community. There
are developers who work for
or are software vendors: their
primary business model
comes from the sale and
support of applications. There
are also developers who
work for or are, what I will
call, and ‘tool makers.’
Toolmakers create
applications for their
company’s or their own use.”
