I'd like to brainstorm with some others on what you think are options for "incentivising" users to use a site in a community. eg. things like user retention, and increasing the odds that people are active on a site.
Other than a point system, what other options are there?
I see this site uses points... but I wonder, does that really help? For instance, I use this site more for the sake of helping others, learning, and thinking... than for the point buildup.
