I was willing to try it, but now I'm not impressed with what it offers. The negative votes add nothing to the discussion. The positives can be handled other ways, too. Doesn't seem to fit in with the use of this forum.
As a “yes” voter, I concede it’s kinda nice to be able to +1 (like button) something but may not have much juice to the squeeze and it begins to clutter up an otherwise very clean interface. Unless the sentiment changes, might as well disable it!
Sometimes it takes a while before all changes are visible. Sometimes a "reload" of the browser is necessary. Some changes necessitate a restart of the forum. But eventually it will be gone.
