Somewhat related -- and boy I never thought I'd say this! -- some stuff started changing in my life for the better recently and I decided to get back on Facebook and get involved again (I hadn't deleted my account or anything, I just hadn't posted or interacted in a very long time). I joined a bunch of groups that interested me and more importantly for me, I started making an effort to like and comment on posts of extended family that I rarely get to see in real life.
It's been REALLY positive. Just last night, we had a huge family thread going sharing our family pasta sauce recipes. It.... made me really happy! Now at the somewhat-annual extended family get-together, we'll have something in common to talk about.
I know it's definitely not a substitute for face-to-face interaction, but in letting go of my prejudices just a little, I've found a nice bit of additional joy in my life and hopefully made other people smile at the same time.
