I have a suggestion for a niche you might find explotable: cryptocurrency exchange trollboxes. Maybe a different version that automatically (or only) works for them. Poloniex removed theirs when users complained about the service - others like bittrex or coinbase don't have them. They're things where the sites don't want them (or are too lazy to) but users do use it for support/community too.
