RedFlag : Is an app where users rate the People. It can be your friend/boss/colleague/Ex/Anyone. If you had a bitter/bad experience you want to let others know that, so they don't face the same experience.
Would you guys be interested in this app? Comments welcome.
For one, Yelp is public facing, a public data. I suppose you don't want to have your name out there in public for people to comment on right? So that comparison is not right.
If you want to do the "circle" kind of thing, which is what Linkedln does, then you have to enforce identity and network connection and you cannot allow anonymity.
Third, you need to consider trolls and haters. How can your user benefit from this app? What can they learn from themselves? Teen were/are using ask.fm and Tumblr to leave filtering and offensive comments. How do you deal with these things?
There are ways to improve the score, but I think today people are just too busy to rate anyone.
