About how often you post on LJ:
"I'll post when I actually have something to say"
That's how I feel about LJ. My life is rather uneventful so posting every day or even every week is not on.
But I have to remind myself that being on "social media" requires active participation. So, my goal is to post at least once a month. And if I have nothing new to say I just post some pictures. ;-)
Your end-of-year food sounds very tasty.
