Unfortunately for all involved this stinks. It stinks for those posting that have every intention of putting a post in the correct section and either inadvertently put it in the wrong section or put it in the section that doesn't best fit it's subject matter and gets deleted.
It stinks for us as forum users because I feel this could drive away some potentially great posts for fear of a thread being deleted because of the above. What if I put all this work into a post and zap it's gone and especially when there are useful replies that may help everyone that become collateral damage. It's always bad when folks get frustrated.
It stinks for the OGR folks who have to make this determination and try to figure out what belongs where and then hear about it if it is deleted for not being in the proper area. They also have to take a tremendous amount of time to do this. I'm not sure how many moderators there are for OGR but I'm betting it's not many and with the amount of traffic here it can't be easy. I'm sure this also takes away from the time needed to focus on other aspects of the OGR business.
It's really a no win situation for most involved. There are a few I see happy over this decision and ironically they are some of the folks that never go out on that limb to start a thread but are the first to point out that the thread is in the wrong section with a judgmental post rather than just using the "Alert Button" and letting the forum administrators deal with it.
My suggestion is to really pay attention to where you are posting. If it is a large post, create it in a word type doc so if it is deleted you can re-post to the proper section without losing everything.
