Our blog would be an anonymous blog by a girl who has a boyfriend who is very interested in many sports, yet she is not.
This would be a blogging community, like a forum, where if a person joins, anonymously, then they can write comments on the posts. People will also be able to submit anonymous posts for review, and then the owner of the blog will choose to post it or not.
The readers would be other women who have the same problems, most likely during sports seasons. There could be a special Sunday post and playoff post where during the main game days women could post their frustrations to the blog as comments.
