I found an interesting site.
It has two 'modes'
The first asks you to list 5-6 postive qualities about yourself, and then provides a link for you to share with friends who will be asked the same question. The idea I think is to realize qualities people appreciate in you, that you didn't know you had.
The second mode is more exciting. It's the same as the previous, except with negative qualties.

They ask for a name when you 'rate' someone, but you can just put 'dolan trump' or something. The site's not perfect, you can easily impersonate people and there's no way of telling the strength of associations, but I think it's still interesting.
To make your own, just go to http://kevan.org/johari or http://kevan.org/nohari, pick 5-6 items and put in any identifiable name.
