I also keep a facebook page for similar reasons.
So much of my small town information gets posted there as well as some very helpful groups.
Although there are some nasty people, I found twitter was much worse.
I live in Yorkshire, England and there is a dialect saying about Yorkshiremen who are supposedly taciturn and careful with money,
See all, Hear all, Say nowt. (nothing)
Eat all, Sup all, Pay nowt
With FB and twitt I try to adhere to the first line. 😄
