Hmm. It's primetime on a Monday night in the Eastern timezone. There are 51 people on the AC forum of FT, and no more than say 1000 active forum posters, and no more than say 10,000 active lurkers (very generous guesses, I think).
The ACTT Twitter account has 8,000 followers, and requires no searching to see old posts with useful content.
The AC Facebook page has 340,000 "likes", and requires no searching to see old posts with useful content.
From a pure business standpoint, makes perfect sense to me.
