I don't think she hasn't ben on facebook for a while, either her private accou nt or the official one - the friend request i put in ages ago still says "Friend Requested", so she hasn't rejected me, but not accepted me either
I think somewhere on her facebook page once, she said that she only accepts friend requests from close friends. But that was before she was on Twitter, and she quite often starts following people when they ask her. In fact, she did that just today.
The more people she follows, the more stuff that is of no interest to her she will have to wade through. Or not, and that means she could miss genuine messages that might interest her. The fact that we can get messages to her these days is wonderful, but we must be careful not to overload her. Or she might just give up on Twitter altogether.
I don't think she'll do that, Martin. Anyway, it's her choice to follow people; if it made things that difficult, she wouldn't do it. The HWI birthday link was posted Saturday night/Sunday morning, and she still found it later in the week, when I'm sure she must have had a gigantic pile of tweets @ her by then.
