doc - I will agree with Bryan on this. I think that any rules notwithstanding, if there is a group of close friends or relatives or household who are posting (seemingly in concert), they need to very explicitly make it clear at the very outset. Otherwise, their own credibility is shattered when later someone else points it out.

I think that the bandwidth issue is separate and should be discussed separately. Just a short while ago, people were being requested to post more (rather than a one liner). I think that as more people start posting, one would have to start getting more selective about what to read and what not to read. So some thought should be put to allow some kind of filters. Also one should be very careful about allowing travel agents or other commercial interests - IMO once the commercial posts start, things start to go downhill.
