FB groups are totally different to G+ groups. For a start, they're a misnomer: it's not a tool for you to group your social network with. Instead, it's this really horrid kind of "interest group" idea, except it revolves around you, and instead of people joining, you include them. Yuck.

FB lists are kind of like G+ groups except they're a PITA to setup and you have to go out of your way to use them when sharing something.

Another thing I hate about FB is the way the entire service is about sharing everything. You have to be really really careful not to overshare anything. In G+ I know exactly what I'm sharing and with whom.

Screw you FB. I hope you die in a fire.
