We have removed the drop-down menu from the thumbs up as during testing we saw only a very small percentage of people use it, and there are other way by which to go about most of the functions that were available in that menu. What it is exactly you'd like to do and maybe I can help?
In regards to the number of people that like it, you can click on the speech bubble i.e. Info Page > View All Comments > and then you'll see all the information about that URL.
Hope this helps!
