When I was your age, Pluto was a planet.

This was the Facebook group that first illustrated to me how much fun you can have in a large and very active group. Founded as a tongue-in-cheek statement regarding Pluto's demotion from planetary status, the group now has well over a million and a half members. It features a variety of fun threads such as 'Last one to post here wins!!!! (for pluto)', an irresistible, but impossible challenge, 'The Wrong Answer Game', 'Corrupt-a-wish' and 'Describe the person above you in one word'.

Who will love it: If you're home alone, depressed or just plain bored, you can enjoy hours of light-hearted silliness with complete strangers. Some may even enjoy your company enough to befriend you.

A word of caution: This group can be highly addictive.

Update (29 October 2023)

Although the group is still alive after all these years, it is not very active these days. Which is such a pity. Back in the day, this Facebook group could provide hours of random fun. Go here to visit or join.
