I wonder?

You don't make ANY MONEY AT ALL by starting discussions OR by replying to other people's discussions. You ONLY make anything when OTHER PEOPLE interact with what you have posted in some way. It follows that the more you interact with other people, the more likely it is that they'll want to interact with you, provided that you post something which is worth responding to or commenting on, &c.

I am sorry but I don't notice that because I am just interacting with commenting some others discussion whether I am commenting on my discussion

I can be on here most of the day and only make around 40 or 50 cents. It's really more about the social interaction for me since I don't get much in person.

@dfollin There are people that can be here a lot so they can earn more money.,

You have to do some of both. I make sure and respond to all Discussions of the people that I follow...and then I work on Notifications. I find that if I only post one or two things a day it makes a difference in the amount of money that I make. Three or four works well for me; although the main purpose for my being here is to make online friends. Doing more interacting lets me get to know everyone better...and posting gives me more people to interact with.

Interaction especially active interactions are the key to earn.

I believe that you have to both. You need to decide what works for you.

You only earn when someone responds to your comments, likes and mentions you. When you comment on their posts you help them earn.
