As the leader of a product development team, you write a daily blog to inform team members of questions, concerns, and other developments related to your project. Team members are always encouraged to reply to your online posts, but lately a number of people have been wandering off track with their replies, raising new issues in the middle of a discussion thread, or posting on matters unrelated to the item to which they're replying. The blog is becoming less useful for everyone because individual message threads no longer stick to a single topic. Write a brief blog posting, three or four sentences at most, courteously reminding readers why it's important to stick to the subject at hand when replying to blog items.
