I won't claim to know much about Yik Yak. I contemplated building HighSchoolACB.com, but held up because I was 1) unwilling to subject an even younger, cattier population to the service; and 2) unsure of the specific legal ramifications of building a service that was ostensibly "only for those above 18" and yet targeted at an audience that was clearly younger.
