I have 383. The most I know in real life. Not necessarily well though. FB has got us all talking more though. Some I use to just say hello to I now stop and have a chat.
I think I might have gotten up to 70 now... Possibly. But I am due a cull so this could change. Most of the people on my FB I'm either related to or close to in my everyday life. There are a handful of AB members on there but I tend to have known them for years.
