So I did read the wiki and posts here. It looks like Diggy's game friends/neigbours is tied to facebook - whereas Train station and Seaport you can be friends outside of FB. It's frustrating to have over 1,600 PF friends, yet Diggy can only have friends on FB, if I'm reading all these forums correctly.
Might Diggy be disassociated with FB one day? I love you all, but really don't want to start friending random people on FB just to get neighbors. That was fine 10 years ago but with Privacy issues my FB friend circle is much smaller these days.
thanks
