Sometimes if nothing particularly interesting has happened or if I don't particularly want to write about what's happened in my life lately I'll just link to stuff on YouTube/news articles, etc. Most of the time it's about my life and I don't know how interesting it is, but as of late it's been rather impersonal.
I enjoy updating my LJ though I don't update it nearly as much as I used to. I used to update it on a near-daily basis though these days it's rougly one or two posts a week. Don't know why that is to be honest.
