Hmm... Thank you for your comment, Ruth.

Actually my time zone is not so different from US and UK, for instance. About interesting topics I don't believe that, because when you are learning another language is natural to write simple things with no great context. If we check it out we can see a lot of posts in that way.

Hi Moa
I never saw any entries by you before.I think it depends on many things.It depends on your time zone.Maybe you are posting when the native speaking countries are asleep and by then time they get up your post is way down on the list.Maybe you post long pieces or pieces that are not interesting.I personally never correct very long passages because I don't think I should work for free.I am a professional teacher.I am prepared to do short corrections.But if people want me to help them prepare for IELTS or TOEFL examination or any other exam that will demand more work I expect to be paid for that help.
I don't know what other reason there might be.If you link to one of your posts I can have a look for you.
