What I learned from these presentations reinforce my previous knowledge on open source with that fact that it can be easily and effectively used to create real world solutions and work is done mostly in communities of people. The new things I have learned which I did not know before is that you could actually have open source communities as small as one person who works alone and the other thing is that open source software can and is used to create for profit software such as in the case of Spongelab Interactive's dragon genetics game. The open source concept continuous continues to innovate development and I think it is just getting started.
