Can a writer survive writing on Mylot?

You could write on line on mylot or a whole story. Either way you could still be earning the same amount. You only get paid for the first response on your discussion. After that you earn only from commenting back on the responses you get on your discussion. So if you want to start writing articles and everything on mylot, then I suggest you don't. If you are talking about randomly discussing, you also can't earn that much for a living.
