Known has released a new version. It seems that I missed 0.6.4.
No huge (to me) features implemented in this one, but I like seeing "Better compatibility with brid.gy". My Obama post didn't pull any discussions in, even though there were comments from Facebook and Google+.
The only negative I've seen so far is that my Twitter integration seems to be hosed. Instead of see a nice little "Twitter" button for cross-posting, I see three different buttons with variable names (@user_token, @user_secret, and @screen_name). I'll remove and re-add Twitter to see if that fixes it.
Update 11/28/2014 3:23pm: Yep, that seems to have fixed Twitter. It seems odd to me that there is a "add another twitter account" button, but no "remove account" button. When I clicked on the first broken account (@user_token) I didn't know what to expect. Thankfully it just asked if I wanted to link my Twitter account, I authorized, and all is good to go again.
Not bad, just confusing.
