While it's something in the right direction, that statistic seems to be updated on delay. My first comment from yesterday only appeared today and my today's comments are yet to be included. That '1 day' delay is a bit of a problem when you want know 'what's happening now'.
Also, it doesn't show any context for the data. What was the comment? What post did it comment on? How many replies does it have? Etc.
My idea would also be to use business rules to sort/filter messages. You can also define transformations in the business rules and I would guess (without knowing the details) it might even be more efficient to first do the sorting and then transformations if necessary.

Thanks! Never thought to search... :)
