Okay... it's interactive time here, kids. I'm trying to compile a list of noncommittal responses. This is what we have come up with so far:

• "You don't say."
  
• "I see."
  
• "Indeed."
  
• "Hmm..."
  
• "So it seems."

Appreciated Additions:

• "Oh really."
  
• "Is that right?" (both from my name twin)
  
• "That is something."
  
• "Interesting."
  
• The old nonverbal noncommittal:
  raised eyebrows, pensive frown, and slowly bobbing head. (those three from Mike "Italicist" Ozmun)
  
• "How 'bout that." (from N. Kumquat)
  
• "There you go." (from tashimoto)

If you have any other suggestions, please leave a comment below.

Thanks,
The Management
