The speaker didn't directly say anything about if he liked the open source model, or anything about what he liked most about it, but I was able to piece together what it sounded like he said. He said he runs the MongoDB user group in Toronto, which right now has about 400 members. They have talks and meet-ups, and it sounds like it is quite a nice community. Based on this, it sounds like he really enjoys the community aspect of open source. Throughout the presentation, he kept talking about wonderful things the MongoDB community had to offer. He really wants the community to grow, and to spread the knowledge about MongoDB. However, it didn't sound like he was to enthralled about how the open source community doesn't document things.
