Based on what I've read (the screenshots are just of reddit and Facebook) this sounds like it would be a genuinely irritating service to use and be a part of.
• If there's any place for a 'social' button, it's certainly not a discussion forum. Typically the content you would be talking about on a forum would be separated from what you might want to post on Facebook (see pseudonyms).
• People love pseudonyms, there's no escaping that. One of the large attractions of discussion forums is that you can be pseudo-anonymous if you are so inclined. If Google Plus failed to convince people to give up their real information, I can't imagine a forum suite would either.
• Profile photos make page loads long and make the information on the page less dense. They add absolutely nothing to the conversation, which is why I presume HN and reddit (large influences in this) don't have them.
• "Flame war control" will just obstruct constructive conversation. Speed and depth of posting isn't an indicator of malice, and will just make users discouraged to contribute.
• A hosted service isn't a feature in this case. I can go and read forums that I was a part of in 2005, but there's no guarantee that a hosted service will be around next week. If the service disappears, so does the content.
• "Banhammers Galore" isn't a feature, see the current attitude towards StackOverflow's moderation.
There's headway to be made in bulletin boards, but I feel you've missed the main issues with the current solutions (vBulletin, phpBB, Vanilla).
