JohnKelly and ownerrim,
This is also true for one of main site. Adding content is giving no incentive at all. In fact, I've been adding very less content in the last 4-6 weeks to the site and my earnings have almost remained same.
However, I've also noted that before 15th Feb., I was getting rewarded for adding new content but in the couple of weeks to follow, I didn't see any benefit of adding the new content and reduced it to fewer changes (added very less content in March). I didn't see any major change in my earnings. I know it varies widely from site to site but can you relate to it?
Is it smart pricing at work where they decide that for one month (or a specific period) they would reward content addition and for the alternate month (or period) they would not? Do we have a pattern here?
