Maybe you are not answering enough questions. I reached to xper level 5 in 5 days, and xper level 6 in a little over a week. These days, I'm earning points at a much slower rate because I have much more important stuff to do than post things on gag. If you have a lot of time try to answer 100 questions a day. 50 questions if you don't have much time, and answer 25 questions a day if you have very little time. You could always increase your chances to getting to next xper level by writing a good take. Your take might get featured and earn 150 xper points. It's easy to move on to next few levels, it takes a much longer time on xper levels 7 and up.
