So, I don't know if it's worth bringing it here (apologise in advance), but the Bicycle blog has posted this about the identity of that NW3 woman:

Of course, no one knows if it's true, but if yes, that would mean JA's friend is running a blog about TH, then it would be quite likely that JA also visited/posted there, i.e. they secretly interact with/troll TH's fans? That would be rather... interesting.
Oh, and NW3 announced that she has had enough and needs a break. Convenient timing again? I don't know what to think.
