Ok so question for people that have been here longer

Here's what I earned a few months back on a daily basis without having to post my own discussion. You might wonder how I earned that much in a day without posting my own discussion? I just interact a lot. I like commenting and responding to people's posts rather than making my own and you earn from that when you interact longer with people.

it depends, start your own discussions and if you get a good number of responses you may get dollars.

Not quite right. The way it works is that your posts (discussions, responses and comments) only earn anything when other people interact with them in some way (by responding, commenting, liking &c). So posting discussions, responses and comments is the only way that you will earn anything BUT not until other people interact with them. When you like, respond to or comment on someone else's post, you are helping them earn money (and, hopefully, they will visit your posts in return!).

This is not for me who is a newbie..

Hard to say,you will have to find out but you can post your discussions too

That is exactly right. The more interactions you make the more money you can make in one day.

You will know by yourself just wait and watch, what this discussion will brought to you in return.

It works by the response you are getting from your discussion and all the responses to your comment. Interacting as well.
