If you enjoy sharing your opinion, experiences, and rants on a multitude of topics then I think that you should try out Postloop. In addition to the interaction that you have with other gurus and/or newbies, you can also earn another source of income. There is no scam or startup fee. By being an engaging user, you can earn Postloop points. And whenever the time is right, you can cash out your points via PayPal.
No one is saying you will earn thousands of dollars overnight, but if you are active, then you can earn enough to pay a few bills. It all depends on how much you put into it. I recently just started and I am having a good time giving medical advice. If you are interested then sign up right here.
Once you are signed up, you will have to decide what strategy works for you. Personally, I enjoy posting on forums more than blogs. I feel that on a blog, the comments are typically short. But on a forum, I can take my time to express my thoughts clearly. Also, I have more experience with forums because I am very active on sports forums and academic forums.
