Being relatively new here myself, I spent the 1st 2 weeks doing LOTS of reading! Then I began commenting on people's posts. I got some followers doing that. You can actually make some money commenting, so its both good for your reputation and your wallet. For now, I would concentrate my efforts on reading and commenting. Once you have a decent number of followers (100 or more) you can start writing posts and earning a few dollars each. After that, continue doing both and grow naturally.
