I broadly welcome the new site :-) I think it's a slight exaggeration to say they will censor absolutely anyone who's being critical about 0S4, but there is a fine line between constructive criticism and the blatant trolling and OS4 basing going on over at AW.
I don't see Amigans.net being a replacement for other main stream sites like here, but more somewhere to go and discuss specific OS4 related matters in relative peace without the usual threads filled with flame wars started by the supporters of other platforms.
