I had to restructure my URL's and had to introduce some 301 redirects. However, then the Facebook likes and Google +1's of the old pages are also lost.
Besides it's a shame those numbers don't show anymore, is my pagerank/linkjuice affected by the loss in likes/+1's?

ps. I know a 301 redirect by itself results in a slight linkjuice loss, but that's not what I'm asking.
