I've two suggestions that would go some way to solving this recurring issue:
1: Remove CB posts from the front page and 'latest posts'. Those who want to chat know where CB is.
2: Remove CB posts from people's post counts. They are not questions and answers in the spirit of the site. They are topics for discussion and replies. [Many in news are too]
People like me joined the site to read interesting questions, to help where possible. Although I miss a lot as I can't use the site when I'm at work, there's very little to interest me or to respond to when I am here.
I don't mind CB being available to those who want it, and clearly I do read some contributions, but when it's all over the entry page it's offputting for me and must be for potential new contributors.
