The ruling is in and being Facebook friends doesn't legally mean you're actually "friends" in real life, this coming after a Miami-Dade judge wasn't sure if she should recuse herself from a case where the judge presiding is her FBF. According to the Miami Herald:
The ruling notes that Facebook data mining and algorithms lead to people accepting friend requests from people they barely know, or are acquainted with purely from professional circles. “Electronic social media is evolving at an exponential rate,” Third District Court of Appeal Judge Thomas Logue wrote in the unanimous opinion. “Acceptance as a Facebook ‘friend’ may well once have given the impression of close friendship and affiliation. Currently, however, the degree of intimacy among Facebook ‘friends’ varies greatly.”
This decision was made on a state level, however, and the final word on what the proper protocol, decision, and regulations on the matter on a Supreme Court level have yet to be reached.
