Bayosphere

I will be keeping my eye on Dan Gillmor's Bayosphere. Dan's trying to set up a news site focusing on SF, all fed by postings of "citizen journalists". I like this idea a lot - and no doubt it could be replicated elesewhere. But I see already some posts are already, in my view at least, well off topic - interesting and worthwhile story sure, but is it SF news? I think posts like this will dilute the usefulness of the site. Of, by and for the bay? Like if I want SF news and go to Bayosphere and find a whole bunch of posts like that will I come back again? I don't know? Maybe? Maybe not?
