I made $0.50 cents on my first day with twenty posts. Is this a good amout?

On the average, 20 post can be done in one hour and with my twenty post I expect to earn a little bit over a dollar. With what I said, you need to post quality response to have an increase on post/earning rate. Then spend a little longer time to increase the number of post. But you are starting better than me, actually. Good luck.

I think it is good, but that also depends on the content of your posts. Some people will post one line of nothing and wnat to get paid. Other post really good and engaging discussions. I posted twice on my first day and earned .19. I think it all depends on how good your posts are.
