The comments posted in this forum, like others, is a conversation. Just like a conversation in person, it can often veer of in other directions away from the original topic of conversation. It doesn't mean that person is looking to criticize some individual part of the information provided, just that something jumped out at them as interesting or they wanted clarification. Just like in a real conversation. For many providers, this place is their "water cooler" since we don't have any actual co-workers.
