There are number of factors coming together that lead me to believe that open source's moment is right now, today, this year. Open source already runs so many things and just last week as Barack Obama was elected the 44th president of the United States, he asked Scott McNealy of Sun to prepare a report on open source technologies as a first step toward exploring the use of open source in government.
When you combine this with the current economic crisis, the maturation of open source products in general, and a willingness to explore FOSS (free and open source software) as a reasonable alternative, these factors are coming together at this one moment in time and it's time for Open Source to step up.
