I like this idea, provided there is some organization too. The need for this is obvious if you look at the AAdvantage 75,000 Citi thread.
I think there should be different threads for the basic, important information regarding the offer, and another thread for the "data points" where (literally) thousands of posts report every step of applying online, what step they reached, the "should I call" and "how do I call" questions, on and on and on.
Don't get me wrong-for those who want to swim through all that, it should be on FT where they can find it. But there should be another place where the primary info is kept to allow those who don't care to go through all that to avoid doing so.
