Quora is a Q & A site that has been online for many years and is well established. They allow experts to work on the site and answer questions people ask. However, these people are no longer earning for their knowledge and the answer they supply to people. There are many different Q & A sites online today that work similar to this. Some of them require a person to pay to ask a question and get their answers, where other sites will just allow people to answer questions and not earn from their answers.
Answeree is a site that has been here for a few years now. In the past, they paid people for answering questions based on how many page views, likes, or best answer they had on the site. Their older paying model took much longer to earn money from the site. Recently, Answeree has redone their site and their paying model. Today you can earn for each answer you supply on the site that is 300 characters or longer. You will also earn if a person likes your answer you've given. The site is working hard to redo their website, help people earn a passive income, and open the site to anyone who wants to join. Where other Q & A sites that pay will make a person pay to ask their question and receive their answer. These sites will require a person to prove they are an expert in one field or another before they are allowed to join the site.
Answeree now has a good paying model for the site where Quora has none.
