Both spokespersons were masters in their fields. Dan is master in Thunderbird community while Greg is master in Linux community. Now it seems obvious that Dan’s talk would be more focused on Thunderbird community. However, Greg’s talk was not specific to Linux community. It was in general for whole open source community. Dan’s talk was more about responsibilities for a member of the community, ; what a member should do and what he should not do to make community and the productbetter. But, Greg was more focusing about on what a community can do and should do to make contributors happier and more satisfied. Though both were targeting different part of the open source world, they both were trying aiming to make the community utopia.
