yep, thread about a thread... big deal.
so - thread started on mn. Another poster tweeted about said thread, came back to the thread and said she'd tweeted about it.
Subsequently posters called for her to be banned for tweeting about a sensitive thread, followed by lots of other nasty name-calling.
Thing is, the thread was public anyway. You don't have to be logged into mn to view it. You don't have to have a button next to each post to tweet about it - all you'd have to do is copy/paste the link into twitter. Once you put your private business on a public website you lose control over what happens to it/who talks about it/tweets about it/potentially writes about it in the press.
To suggest that a poster should be banned for talking about a thread that is on a public website, on another public website is ridiculous.
Mn has hundreds of thousands of hits a day. People are very naive if they think that their private, sensitive business is limited to the few people that post on the threads in question.
And people do discuss mn on twitter. Both in terms of threads/the potential genuineness of posters/the outcomes of threads. It's just that they don't come back on to mn to talk about having done so.
