In general, we like to think of discussion forums (as opposed to official technical support forums) much like do when chatting at the coffee maker or water cooler in the office. It's a nice place to hang out, chit chat, get caught up, but we don't spend a lot of time there 'cos we have more important (read: billable!) things to do. Sometimes we find tidbits that are really helpful but more likely we're just looking to gossip, vent, or maybe find a lead to some better information on a subject
