Using actual social sharing buttons, as provided by Twitter or Facebook (et al.) is a no-go for most performance-concerned or privacy-concerned websites. Too slow, too dangerous. It’s kind of a shame though, as those buttons are nicely functional. An alternative is “share intent” URL’s, which generally link to a barebones page in which to share the content. Jonathan Suh shares how you can fancy those up a bit with popup windows. I like it, feels much nicer.
