the problem with that is there is no secured backup of the present forum if you just rely on a couple people to do this backup. what happens if they go offline for some reason. then they're not doing backups anymore. how long until people realize that and someone else takes their place. i wouldn't say bitcointalk needs to be decentralized but its data needs to be maybe. but as we have seen, that's easier said than done and we might be stuck with the centralized pay per month plan. i have lost interest in this because it seems like it is a very high cost factor for any type of decentralized storage unless it is the users who are paying for it somehow.
