Feature request: Author total likes

[ste7enm]

Hey there--

Wondering if it might be possible through some arithmetic to calculate the total number of likes an author's posts (in total) have received to display it on their author profile page?

The use case would be a multi-author site to gamify authorship and have bragging rights / top authors (not necessarily to display as a list, but if an author wanted to compare their likes to another's).
