everyone start a new discussion about mylot earning.

From what I understand it all depends on how you write your discussions and responses to other discussions. You cannot just write one or two words. You have to have a well thought out response and care about what another person is writing about. If you have advice or experience with what they are asking about then you can respond to them in a thoughtful way. You will make more money by doing this.

Maybe the earning is not yet updated. That happened to me because one time i thought that i did not earn anything when i posted like 5 responses but after 2 to 3 days, i saw my earnings increase...

I suppose if you do simple one or two words or just one or two sentences, you are not going to get much money. Saying 'wow!' when someone says that they went to the pet store and there was this lovely puppy doing tricks, will not get you to much money. You do not get paid for comments either. The best thing to do is to write quality posts about five lines or more, with detail and to give responses that also are five lines or more. You can of course get away with four or three lines, because some posts do not require many sentences, but they have to make sense.
