I really only skimmed the comments on The Beat and Bleeding Cool, but if she started the discussion, it makes sense that she would want to see it through, however it may have progressed.
Truthfully, I can totally sympathize with doing that. There have been a number of times where I've started or gotten myself into an argument/discussion where I'm intensely interested in where the conversation goes, and I'll obsessively reply to anything to which I have a response. (I rarely have the energy for that kind of thing anymore these days, but hoo boy were they fun when I did.)
At any rate, I'd rather not ascribe any particular intentions to the situation or the people involved.
