Shareaholic is an awesome browser extension that helps you share stuff you discover across all of your favorite social bookmarking sites. And as of today, that includes BuzzFeed, so if you're already using it, you should add us to your preferences (it'll take a few more days before we're on the Firefox version, though). Shareaholic is available for all the major browsers, and it's worth checking out if you're someone who uses browser extensions!
This has been your hopelessly geeky public service announcement for the day. Now back to kittens and Bieber.
