The desktop site has also had some changes to make it more friendly and interactive. Keep checking up on it!
Perhaps I can make the DSi fetch comments from Hatena Star as well; but don't get your hopes up. Most likely, the Hatena system will be completely isolated from Sudomemo.
I also don't know if I will be able to credit creators with stars to their Hatena accounts; currently stars just go to mine (I'm not complaining :P). I've sent a tweet to Hatena asking about perhaps getting user blog tokens so I can credit users with those: https://twitter.com/Sudomemo/status/567196260965552128
