Hey Steve,
Thought you were sitting this one out

Seriously though, it's good to think about how we communicate here. On another space
http://www.cabweb.net we have found not everyone feels able to participate in discussion in a space open to Google and the Internet. The geographical distribution of our public space are similar to this site see
http://moodle.org/sites/ whereas the geographical distribution of (at least some of ) the discussions in a closed space is different. We don't all have the freedom to feel comfortable making public posts.
Perhaps we should be thinking about how to encourage underserved communities to contribute. I think that making 'political' posts the '
elephant in the room' whilst apparently making posting easier and less problematic, could have the opposite effect of setting up hidden obstacles.
So what do I think? I think that inter-cultural communication is truly challenging and requires questioning of assumptions (our own and those of others) and tolerance from all. We can ignore trolls (when we spot them) and try to err on the side of giving a voice to all comers.
