Updated to the latest version of Known. Long overdue.
Ah, a fellow former Chyrp user, and now fellow Known user. I really enjoyed Chyrp as well, the selfhosted Tumblr as I like to think of it. It was great, I themed it, but didn't have the chops to develop for it. Known is great too (:
Yes, I noticed the email that Known sends to let me know that someone interacted with my post, had the quoted content and your comment mixed into one paragraph. Not sure where or how to fix that, but it could be that you need to deploy the fix you mention to more post types.
Updated to the latest master of Known via github, and also updated PHP on the server hosting my Known instance. Turns out it was running PHP5 0_o
