There's a couple of threads at the moment - probably more than that - but two I've noticed in particular where there a poster has gone quiet.
The threads have continued, but not as a chat or a discussion on the topics raised - but basically just hounding the OP to come back and update.
I'm as guilty of blatant placemarking as the next person for a thread where someone is engaging on a living drama. But, particularly in one case where the OP has come back to say 'I don't want to update' - what do people get out of this? They aren't coming back and a bunch of people asking them to won't make them.
