I am wondering if it is planned to provide the user with methods to control the content they see, ie; filtering the topics in a group or comments in a topic based on various criteria including keywords.
I looked around to see if this has been asked, or if there was a roadmap document, but did not find anything. (this is no criticism, I do realize we are early in the dev cycle and I cannot image just one person being able to do all this!)

I do hope so. No matter how high the quality of the topics/comments there will always be things a user may not want to see.
