I had one simple idea about telling friends about arts and technology events. People in the community suggested everything else to us, and that's our theme. We're really run by the people who use the site. We just run the infrastructure, and help out with problems.
My understanding from talking to a lot of people in the business has been that it used to be that a newspaper was considered a community service. Now they're being run as profit centers, and they're trying to get pretty high profit margins. As a result, investigative reporting has been seen as a problem.
We don't think of ourselves as do-gooders or altruists. It's just that somehow we're trying our best to be run with some sense of moral compass even in a business environment that is growing.
