My house my rules
Let me be the first to say, "Badges! We don't need no stink'n badges." Yes it needed to be said.
Currently I'm setting up a site powered by Geeklog and as such open to comments. My considered opinion on the issue of blog ethics is summed up as my house my rules. Unless a site is overseen by a governing body the rules of each site stem from the owner/editor. There's no need to comment on the extent of the hubris in the announcement from Messers Wales and O'Reilly.
Don't like what's printed don't read it. I ( Quirk ) was banned from slashdot for reasons I was never able to ascertain. I wrote three emails trying to find out why, didn't get a clear answer, left and never returned. The prerogative to ban someone or censor material should rest with the site owner. If you can't deal with criticism or rejection then the time you spend bemoaning your fate on the web might be better spent in therapy.
just my loose change
