There have been a few 'national' sites that I would consider successful. Kelly's Airsoftguns.com, and Brian's Airsoftzone.com were 'national' sites that I really liked. I did not like Pikachoad's Airsoftplayers.com (but I'll confess that PikaChoad annoyed me greatly). I lurk a little at Airsoftretreat, and every time I log in, I am reminded at why I don't lurk there often.
I'd really hate to see a massive influx of bleeding retards who are incapable of using the search button, and who have never heard of Google. I despise people who are incapable of doing research and speaking English. I can forgive poor grammar/spelling when people from Portugal or China are posting here. I can not forgive the same in Americans.
