I was excited when we came to this subject because I already have and use my own Facebook account. Here is a link to my page. https://www.facebook.com/#!/ I use it to keep up with my family, friends and even my church.
We also have a page for our library, here is a link for that.https://www.facebook.com/#!/pages/Hughes-Springs-Area-Public-Library/10150162992715008 We promote programs, feature new books, and advertise fundraisers.
We have not worked with Twitter yet but I can see in our newer fast paced world where this could be a tool worth a longer look.
Needless to say there are sooo many more things about Fb and Twitter that I need to learn.
