At this point in time, I'm not certain this update has incorporated any sharing data (or fails to do it effectively). I work with a site that soared during Panda that doesn't have a FB page, no share buttons, etc; and another site that tanked, which has a FB page with 1,500 fans. Granted, these are just two examples, but I have seen more.
There are more places and means than facebook whereby people ( real breathing non webmaster people ) like your mother can be saying nice things about your site ..
I have a site that is #1 from 250,000,000 for its 6 letter KW domain name ..4 of the other entries on the first page of serps for that keyword are fora with posters who use that KW in their posts ..two of them link to me..
My logs show others ..but deeep down in my logs ..I'm going to go reach out to them , engage them ( not spam the fora ..just comment upon their comments , make a conversation like the cluetrain says ) ..because even the mentioning of my KW term by them is helping me ..a conversation even if its only two posts can only improve matters, ( OK I'm at #1 but who knows tomorrow ) ..or help to "proof" me a little against the future algos..doesn't seem to need much time to do this..see who is talking about you ..talk back ..keep the conversation going a little ..
Many of us spend more time every day on here, than we do talking to those who are talking about our sites ..
fresh "engaged" conversations ..G likes them .
