The Twitter account is not fake (you can search for dNote's posts here and see that he references it and that it is official).  Most of the devs are based out of Asia (you can verify that through an old DuckNote interview in 2014 you can Google) and I think mainly China (based off of speech patterns and one comment dNote made in the past here).  I think that this adds to why the communication is the way it is, besides being busy, and I also think that this is another reason why the project holds so much promise.  I think Asia will take the cryptos to a whole new moon with projects that many Westerners have overlooked due to societal differences, regional perceptions of the market, the worth of BTC/CNY vs BTC/USD (BTC is essentially worth more to them).  It makes sense to me that companies in Asia are more apt to invest in XDN with real world projects, and it makes sense culturally why they are about the tech and development rather than updates every day on a bitcointalk forum. Anyone who visits this forum often knows it is troll infested and while a good starting hub, basically cancer.  Still speculation on my side though.
