The value of FLOSS is not reliant on the software itself, part of that value comes from that community that develop and uses the software. Much of the value of a FLOSS project comes from the community that it creates around it, since this community is the main force that moves the project forward and develops it according to what they dim to be the best road.
In many ways, any FLOSS project is a reflection of the community around it. The more committed, dynamic and functional the community is, the better the project will be. The strengths and weaknesses of any given project are those of the community that was built around it.
The way a project moves, in any way, is a reflection of how the community works together to get things done. The better they work as a team, the software they put forward will be better. The bigger the project is, the more vital it's to have a community that knows how to work as team and contribute what they promised on time and shape. There is no other way to make great software, since no single person can coupe with the workload that would mean doing everything by himself.
That's why many times projects with promising ideas fail, because the community around it didn't manage to find an effective way to work toward the common objective. There are some other cases where a community willing, and able, to work as team don't get their act together because their project wasn't based on a solid or workable idea.
A strong, committed, and active community is one of the most valuable asset to any FLOSS project. I would rank it to the same level to the software itself, since both are interdependent. You can't have one without the other, that's why it's of vital importance to take care of the community that drives the project forward. There is a real need to listen to what the community has to say, and more importantly have an open communication line with and among it as a whole.
Not paying attention to the community, is one of the best way to ruin any project since losing it is a fatal shoot. Once you lose the community, is almost impossible to build it back up.
