I think what you want is (object id, object id) - with SOA object
references (which are still subject to refinement) - otherwise you'll
be in the business of updating thanks rows on every user rename, which
isn't a terribly interesting thing to do.
I also have some suggested tweaks to the API:

This should be set based - eg.
get_thanks (object id[current user], object ids[multiple things to check]):
returns a list of (object id checked, did-current-user-thank,
total-thanks, [object ids of some thankers])

- mapping the current user to a obj id
- checking the current user has access to the relevant urls
And so forth - rather than querying each comment, query them all.
Rather than querying each bug in a bug listing, query them all.

I think it looks quite nice as a concept. Maybe ratings and reviews
has some need for this (or an in-house implementation they'd be
interesting in dropping and migrating onto a common service?)
