I'm on Twitter with the handle @SpiralGalaxy . You can see lots of cute pictures of my kids on Facebook. I also maintain an active LinkedIn account focused on my engineering work. I've started up a Tumblr to keep track of my various reading lists. And I keep pretty pictures and ideas for craft projects on Pinterest.
I used to keep a blog with reviews, reading lists, and commentary at spiralgalaxyreviews.blogspot.com, but it has been overtaken by other platforms.
