The DFW CFUG had a really great meeting last month about open source in general, and specifically as it relates to CF, so I thought I'd pass along a the presentation I put together.
It contains my general thoughts about open source as well as a list of some open source CF applications that you might not be aware of. If you have any comments or questions about this presentation (it was thrown together pretty quickly), please let me know, and particularly if you have good open source CF resources, links, applications, etc. that aren't on my list, please tell me. I'd like to keep a running link list to spread the word about open source CF applications.
This has kind of turned into a crusade of mine as of late, because I get a bit annoyed when I see CF-centric sites using PHP applications. Most recently someone started up a "worldwide CFUG" and it's running PHPBB. Its creator had all sorts of reasons for doing this (none of which were valid IMO other than perhaps the free hosting issue), but even CF Open is running on a PHP application. We all need to work to change this situation!
