My own opinion is it should be whatever is on ones mind, if they have the need to share, or vent ,or ask for help, or tell their story or just share what is going on in there life or in there quit . It is how i have gotten to know other Ex'ers .
I don't think there should be rules or comparisons . Sometimes a blog is written so well and is so inspiring that it is shared to the Best of Ex . I don't think others should feel intimidated if they cannot "compete " with the Best .
I did write many more blogs in my early weeks and months because I needed that daily communication and support. Now I mainly read and comment on the blogs .
