Are you also active on Google+? It's my experience is that the social endorsements from G+ is more effective then from FB (+1's vs Likes i.e.). The thing is that FB keeps it mostly on their domain and it's value is most relevant there and thus doesn't extend out as far as G+'s social layer.
Sure 10K Like helps as search engines pick it up and it creates a buzz. But when you connect your content on the web to your G+ profile, are active on and around G+ or at least publish your blog posts etc there then it's really effective for faster indexing and high ranking in Search and it makes it all look consistent with the rich snippets as a bonus.
Not only is a +1 more effective for a higher ranking but the social data of various sorts can also i.e. be used in Adwords for example to be shown along with your ads generated from Adwords on Google and on partner sites. And for I said enough without mentioning mobile (in-app data, Google+ Sign-In and app distribution to Android etc etc.
Just some reasons why I invest more in this then FB!
