I posted a new suggestion on UserVoice:

Ajax Link Ratings

When I clicked on the rating icon to register a vote, I was surprised to see a brank new page compiled just to tell them their vote was counted, then forced them to click something to go back to the directory.

Ajaxify it!

I wasn't sure where to post ideas here, being new, so just delete this post if beyond the scope of the forums.

We are planning to introduce ajax in many places in JV-LD in the coming versions. This
request will surely be taken up!

FYI: And we are moving this thread to the feature requests forum for JV-LD.
