Pretty cool that I had the opportunity to talk with one of the associate pastors at my church this morning about the difference between Internet Explorer and Firefox. He had some issues with IE and I recommended that he download and try FF. He had never used it and he had it up and running with imported bookmarks and all in about five minutes.
Just because there is no charge for either browser doesn't mean it is free. Trust me, if you've ever gotten a Trojan Horse or any other worm virus via IE it is NOT free. There is a lot of pain and suffering that happens to you and your PC.
We also talked about the difference between a monolithic, proprietary license company and a volunteer community centered around the interest and desire for good software.
This is the foundation for any group based on open-source/religious/social/hobbyist community: love. And when you love something you set it free.
