snydeq writes "InfoWorld's Bill Snyder examines what appears to be an open source job market boom, as evidenced by a recent O'Reilly Report. According to the study, 5 to 15 percent of all IT openings call for open source software skills, and with overall IT job cuts expected for 2009, 'the recession may be pushing budget-strapped IT execs to examine low-cost alternatives to commercial software,' Snyder writes. But are enterprises truly shifting to open source, or are they simply seeking to augment the work of staff already steeped in proprietary software? The study's methodology leaves too much room for interpretation, Savio Rodrigues retorts. 'That's why the 5% to 15% really doesn't sit well with me,' Rodrigues writes. 'I suspect that larger companies are looking for developers with a mix of experience with proprietary and open source products, tools and frameworks,' as opposed to those who would work with open source for 90 percent of the work day."
