is it really worth the time to post long in mylot?

Mylot advices quality posts but it does not specify how long the posts should be.

Yes. I already have 3 posts that is very very long. My earnings increased because of this posts. Even if you replied in such discussion and it is a very long reply, you get a much deserved amount.

The answer is yes you do get paid more for long posts. Doing an average of a 300 to 500 word post helps. The more information regarding your topic or someone else's topic - helpful information, encouragement and sticking to the topic - the better you get paid. I first started Mylot and also in the beginning I was making less just by small posts. Sometimes you will get paid and sometimes you won't. Having only a sentence or a paragraph topic won't do any good. When you start a topic try to find one to make sure you have something to discuss that will be a long post. Think of it like writing an article on a magazine, or a journal, giving specific information and provide things that can attract people what you're talking about. There are those who make long posts so well Mylot is paying them good. You can too - so keep up the good work I know you can do it.
