People still think an abandoned project, eg. a dead open source project or weblog, are failures. They instinctively shy away from starting half-thought out projects because they don't trust they have the time to make a good job of them, and that therefore such things are useless; or worse, an embarrassment. How lame to have failed or given up on such a project.
This is just Finishedness thinking. (AgainstFinishedness)
Even though such projects don't achieve their intended aims, they may still be contributing to the overall vitality of the network. An abandoned project may still
- excite someone else to attempt a new project
- teach the person who created it many things
- bisociate or link disparate ideas which had never been linked before, thus strengthening the connection between them
There is a kind of danger. If you have too many good ideas and can't decide which to go for. You end up achieving nothing. This sort of failure can lead to many unfinished projects.
