Just for the record, I'll post my thoughts in here...
Although I understand that these "regional" threads may incentivize newer members to post and get to know people in their area, where they would usually feel too intimidated by the constant whoring by the regular group of 20 or so vocal members to post elsewhere, the question begs to be asked whether it's a good thing to allow this segregation to occur right from the word go.
One member admitted that 80% of his posts were in one of the regional threads. That sounds a loud alarm and starts a rotating flashing red light in my mind. This is NOT a good thing. But is it better than having the member post 80% LESS instead because he doesn't feel like he can post elsewhere? Hmmm... interesting
Another issue is that I have found in spending 30 minutes browsing these threads, is that 90% of the posts are people trying to organise meet ups. Now why in the world, would you organise a meet in a regional thread? NO-ONE except people who hail from that region would read that thread, so you're only advertising that meet to a tiny subsection of NSW. What is a cruise was organised in the Hornsby regional thread? Only the Hornsby people would read it, but what about the Northern Beaches crew? Quite a few of them would probably like to go along, but they would NEVER hear about the meet, because it's hidden in some stupidly exclusive thread!
Which leads me to another thing. If we were to have regional threads, they would HAVE to be regional. Campbelltown is NOT a region. Newcastle is NOT a region.
So in summary, I think that regional threads would be okay, but we need to SET the regions. You can't have people constantly making new threads and segregating NSW into smaller and smaller chunks until you have single suburb threads. That's utterly ridiculous.
Have PRE-DEFINED threads like "Northern NSW" that would cover the entire area from The Entrance and up. and "Northern Sydney" That covers the Hornsby, Northern Beaches, and the rest of the Kuring-gai area, etc etc.
Last of all, NO event organisation must occur in these regional threads. Want to organise a meet between your central coast buddies? Make a thread in the Events section so people outside of the central coast have the option to come!
