Personally, I think Answeree could attract more users if it will have interesting things going on rather than the plain A&Q site. Say if you wanted to take a break from answering questions, then there are other activities for you to earn bonus points. A daily log-in bonus provided the user gets to answer 3-5 questions may also help in encouraging users to visit the site on a daily basis. These are just some of the things I've thought of.
