What go me involved with open source was freedom. Their is no limit to what I can do with open source. If i wanted to learn how to write a program or configure a private server to test concepts and ideas out, I can do that without it costing me an arm and leg. Because of the freedom that open source provided, I was able learned how to make web page, write php programs, learn out to properly secure a firewall, create a web server, DNS Server, DHCP server, syslog server, etc, just with the equipment I had at home and with open source programs and operating systems available. Will I ever go back in short H3LL NO :)
