Another great point - monetization. It is not impossible to monetize this website via ad words etc, however for proper moderation you would definitely need real funding/cashflow.

I didn't clarify this anywhere, however I would like to now: I never intended to make money off this website - at all.

It is just a fun challenge and a problem I wanted to solve for myself: How can I find an explanation of something in only one sentence (currently, it's all over the internet and not in one central location). So 1Sentence was my quick attempt to fulfil this need.
