I sense traffic of this blog w/o a present reason. Hmm. What about this, brief musings about trust:
Each software, each website, each social platform, each community building effort is a matter of trust building. You make a social promise to continue the effort, and to care for the commitment of the users or community members.
It is easy to offer more to your community. On the other hand, it is quite difficult or impossible to take something away, or to close down or end the product or community without disappointing someone.
