I'm on Twitter only to get tweets regularly from a couple of sports journalists. I don't send out tweets at all and am pretty ignorant with how Twitter even works.
I use FB mostly to keep in touch with family and a handful of former co-workers and friends. I have 34 Friends and that number hasn't changed much over the years because I don't want it to. I'm not one of those people who is looking to have hundreds of names on my friends list. Thanks to Facebook, I was able to "attend" a funeral this past Saturday. My brother's wife died of ovarian cancer in Wichita last week. None of my siblings could attend in person so being able to see and hear the service broadcast online was a blessing. I do a lot more reading than posting on FB.
