Hi all. I'm Larry Cafiero. For more about me, biographically speaking, you can visit http://larrythefreesoftwareguy.wordpress.com/about.
But why I'm here: I'm a journalist who backed into FOSS in 2006 during my campaign as the Green Party's candidate for Insurance Commissioner in California, finding that I could do just as much with free/open source software than I could with commercial software.
The philosophical and social ramifications of free software for all was too intriguing to pass up, so I have become an evangelist for FOSS and I find Ubuntu an excellent vehicle to bring free software to all (as an aside, I am a Debian and Xubuntu user -- love the Xfce desktop! -- but I also use a wide variety of distros, including Fedora, OpenSUSE and AntiX Mepis on both Intel and PowerPC architectures).
I also organized Lindependence 2008, which took place in Felton, California, in July 2008. It provided about 300 townspeople here with distros (mostly Ubuntu) and FOSS programs like OpenOffice.org.
I live in Santa Cruz County where I make my living as a copy desk editor for the Santa Cruz Sentinel, but I also have an office in Felton called Redwood Digital Research. RDR provides small business/home office clients with FOSS solutions to free them from Redmond's hegemony.
