I disagree with the bolded.
90% of the Southeast forum is filled with people from NC/SC. And while I'm sure most of them are fine people and I don't mean to be rude about this, in large part the extent of their discussion is either whining about the Summer heat/humidity or hyping up snow (which is crazy to me given their climo, but to each his/her own).
In Georgia, a state of over 10 million, there's a grand total of 3 semi-active posters in that subforum and then 1 additional poster who only posts occasionally, 3 of which are in Metro Atlanta (the 3rd fastest growing place in the country with 6 million people and counting) and 1 of whom is a mod. And even those users are more often than not MIA when there are severe weather events in the Summer (which is their perrogative). I have yet to see any posters from MS/AL/TN/FL.
The Midwest subforum isn't perfect, and I can't speak on the Mid-Atlantic forum, but at least the geography of the posters in this region is evenly spread throughout the entire region and there's always an active group of posters tracking severe weather events AND winter storms. There are also more meteorologists on this subforum too (although, admittingly, some of them are too quiet and the others may not be the most professional).
