Interesting, I've been on steemit for quite some time now and dont think I've been on dsound. I might create a user and try it out, from what I understand you should be to create a steemit user using this account you are posting from and then set yourself as the recovery account for your dscoud user. Never tried doing that though, but should work in theory. You would be able to regain access of your account if dsound got hacked and someone stole your key,but of course you could lose your funds.
