The proposed forum might be very lightly used, might become unreadably harsh, or it might become a beacon of light onto the blogosphere. I just don't know. If a forum is created, the posters will decide its fate, not anyone else.
That is the point. It is an IBB forum, not an airline buying additional aircraft to enter a new market. If it tanks, is unwieldy, underused, or otherwise needs to go, it will go. I can't imagine it having less "surviving posts within the past two days" than Travel News typically has, but if that forum survives, this one should be given a chance.
