I think sites that are intended to be an alternative to something else, but are too specific such as "guns", are a problem getting people to move to. Facebook, for example, but the gun version.... who of my friends and family would I be able to get to migrate there? At most, I think I could count 4, and that's if they even bothered to migrate there with me. So, I would be able to see the cat and vacation pics of 1 relative and 3 friends, that's it. So, in reality, it would probably be just me and I'd have the most boring gunbook feed, not even worth checking. Facebook is only useful because everyone is there and I can see what crap they are up to and promptly chat with them. To be a viable alternative, I think it would still need to accept everyone for any topic, but not all the stupid garbage like censoring people's posts and taking a dump on anyone with a free thought all the time. So, Facebook, but free. But, you still have the network effect problem, trying to get the ball rolling and the whole thing started and have it reach critical mass. And while it could claim to be accepting of anyone's beliefs and not censor them, let's face it the lefties that you know won't really care about that since they aren't getting censored anyway, and being around alternative thoughts upsets them. So, lefties would not migrate to the FB alternative... it would still just be conservative and libertarian types. Again, most people I know would not migrate. For everyone to want to migrate, FB would have to start shitting on all the lefties too. So, I highly encourage them to do that, just go full retard and piss off everyone. Only then we may have another viable platform emerge.
