If you search on google or somewhere else then you may find that answeree is a meaningless word. You may even get some other suggestions too like answered, answerer etc. I had seen many people using the word answeree taking into the meaning as one who responds.
If you are asking about the name of this website Answeree.com then I would like to say that we are in the making of this word 'Answeree' a meaningful word through our community!
I think that helps.
