You don't !!!
That's right. You read me right.You don't........... blog about the topics, that I want you to.
Wait. We ALL have the right to blog about the topics we want to ?
AND that no one is forcing any of us to read blogs that we are not interested in ?
Oh !!! Well, that certainly makes a huge difference. Sounds fair to me.
I guess complaining about other's blogs (as long as they follow the site's rules) is fairly silly then.
I have an idea. Go write a blog that is on a topic that interests YOU, or if you are incapable of doing that, read one that DOES interest you.
