On the other hand, often people who post opposing opinions are often called "trolls" or "basher" without any dialog having taken place. It might be just someone sharing their opinion with a member who has asked for it. If a member asks for advice about which wls to get, they need to hear from opponents as well as proponents. Posting about a true experience that was negative isn't negativity per se, as long as it's within posting guidelines.
On the side bar, there are lots of status updates, topics posted and they may be in a forum that isn't relevant to our particular situation or for a different WLS. It might be good, at least on the Lapband forum, that the sidebar topics be related to Lapband topics only.
