question?

Why do people read other's poems and journals and not comment?
It drives me crazy!
If your going to read what someone wrote you should tell them what you think about it. Don't you agree?
I really like to hear what people have to say about what I write. I mean isn't that the point of joining mibba? To have someone comment on what you write?
So why don't people do it? I mean whats the point of reading it if you don't?
Sooooo pretty pretty pretty pretty please with a cherry on top start commenting on others stuff. I mean sure you read it but the author posted it for you to tell them what you liked or didn't like about it and what they can do to make it better. Surely I'm not the only personn who feels this way. Am I????
