Im just wondering why people sometimes answer or respond to posts about topics that they have no interest in. For instance, I am not going to join in on a discussion about interior decoration. Why? Because interior decoration is a field I have no interest in. Therefore I really couldn't give any meaningful feedback and so I would simply not enter in on such a discussion. Such a conversation would be for people who are interested in interior decoration and who maybe want to pursue it as a career, since that wouldn't be me I wouldn't participate in such a conversation.
