Have you pondered the moral implications of your startup?

I'm working on a start-up that, if successful, has potential to be a major reference of human knowledge (think wikipedia in terms of vastness and impact, although it isn't particularly similar to wikipedia). We won't be able to control who uses our resource, and as it is community-driven, the specific direction our site will take is unknowable.

Call us naive optimists, but we're convinced that, for the most part, our startup will be used for good purposes. We're strongly against censorship, and we don't think censorship really works on the web anyway, so we'll be leaving this up to chance.

An example of a startup that might be slipping to the darkside is Reddit. I know Reddit was backed by YC, so anything perceived as a bash might not be well-received here. Nonetheless, I'm certainly not alone in thinking that the Reddit community has taken a turn for the worse. My biggest problem with Reddit today is its lameness, however, Reddit is not just lame, it is increasingly used to propagate toxic misinformation and hate speech. I wouldn't be so troubled if I didn't see so many members of the community at Reddit embracing those sentiments.

I'm pretty sure that the Reddit team doesn't condone hate speech, and I'm not proposing they censor the site (it wouldn't really be possible, anyway), but it makes me wonder:

What do they think about this segment of the community they built? Do they wish they'd done anything differently? Is there anything my team can or should do to minimize our site's use for what we consider to be immoral purposes? Has anybody here spent much time thinking about this issue? Have you come to any conclusions?
