This is a very good point, Chrissy (and I'm not on Facebook either.)
I do know it's a very thin line and hard to know where to draw it.
I appreciate your perspective, as I'm very careful with my personal information as well (guys get mad that I don't just hand out my phone number or even email address unless I've communicated with them on a site such as this for a long time.)
I often struggle with knowing how much to share vs. common sense and personal protection.
