Well, blogging is freeway to share your ideas and becouse it's free you cannot pushing and rushing the writer to write articles based on your need. One thing we can always stand on is, "writer is also human being" , they need to pay bills. So If you have ever pushing and rushing writer anywhere else it is soo unpolite, and it' always better if you ask him/her directly and give some rewards of what you have asked for.

Have a nice blogging!
