Another idea, if I may...
If one of the purposes of giving acorns is to highlight the better posts, then the exclusion of anonymously given acorns on the home page skews the results, because they are never acknowledged with the present system. I can't imagine any anonymous acorn giver that would not want their acorns counted (while still remaining anonymous), as it enhances their intended objective, as well as the "good vibes" recognition to the recipient. Including anonymous acorns in an "All tallied" count would (at least partly) remedy this.
Hopefully, Dave, this would be an easier task to code?
