It seems to me like there are many more responses to the
"is my quilt ugly" and "I need to vent" posts
than to the
"I made a lovely quilt" and/or "Everything is going well" type of posts.
As someone else has said - this may be the only place for some to vent or get a sympathetic ear or reassurance. If you don't want to do a "there, there" - it's okay. Move on.
