How many can I join?
Have you ever wanted to know how many Facebook Groups you can join?
You might be surprised to learn that you can join 6,000 Groups, as stated on this Meta help centre article.
The limit was increased from 300 to 6,000 in May 2013 by Bob Baldwin* (Quora answer below).
I ❤️ that Andrew “Boz” Bosworth upvoted his answer, a lovely #InsideFacebook insight from the time.
