Location: United Kingdom. Further refinement depends on work.
Tumblr/Goodreads/IG/etc: I use nanila everywhere I'm active (Dreamwidth, Twitter and Flickr)
Snapchat: I have heard of this new-fangled thing but given how long it took me to pick up on WhatsApp I don't expect to start using it until 2020.
Describe yourself in five sentences or less: I'm a spacecraft engineer, a dual national and a parent. I think of myself as a Londoner even though I no longer live there (though I still work there). I like to bake. I overuse parenthetical interjections.
Top 5 fandoms: I'm not very fannish.
I mostly post about: Navel-gazing about my life, photos (kids, cat and selfies), travel, work and politics.
My last three LJ posts were about: The December Days meme, which I'm doing with photo prompts.
How often do you post? How about commenting?: I post 3-4 times a week on average, sometimes more. I've never left LJ for longer than a couple of weeks. It's a fairly complete record of my life over the past 15 years. I answer almost every comment I receive and try to comment on friends' posts regularly, or when low on energy, press the "heart" button to show that I've read it. I would be delighted to make new friends in the revival.
