According to my calculations, FlyerTalk will surpass a half-million posts sometime in the next few days. At midday today, here's the scoreboard (compiled while on hold with an airline):

Talk 191,414 38.9%
Airlines 229,642 46.8%
Hotels 38,906 7.9%
Car 1,900 0.3%
Credit cards 7,762 1.5%
Phone 1,592 0.3%
Global alliances 9,186 1.9%
Discontinued progs 7,738 1.6%
FlyerTalk Support 3,462 0.8%

Total 491,602 100.0%

Doc, who's nearing 20,000 posts, accounts for 4% of the activity on FlyerTalk or about 1 in every 25 posts. In my view, Doc, they're all quality posts.
